João Salavisa 279e15b318 feat(plugins): implement Host data API write RPCs (CreateTask/UpdateTask/SendMessage) (#1970)
* feat(plugins): implement Host data API write RPCs (CreateTask/UpdateTask/CreateComment)

The api_write manifest capability was a stored no-op. Wire the deferred
phase-2 write RPCs (ADR 0043) so closed-loop plugins (Sentry->task,
Slack slash-command task creation, refactor fan-out) can create and
update tasks and post comments.

- SDK: Host.Tasks() gains Create/Update; new Host.Comments() writer;
  CreateTaskInput/UpdateTaskInput/Comment DTOs (pkg/pluginsdk).
- Gating: api_write:tasks gates Create/UpdateTask, api_write:comments
  gates CreateComment; undeclared -> gRPC PermissionDenied, per-method
  and independent of the read caps on the same resource.
- Writes route through the first-party service layer (task service for
  tasks, office service for comments) via backendapp adapters, never a
  repository -- so task.*/comment-created events fire and WS updates.
  Server stamps source="plugin:<id>"; CreateTask resolves workspace/
  workflow defaults and best-effort honors start_agent; UpdateTask uses
  a conservative title/description/state/workflow_step_id mask.
- Fixture plugins exercise a CreateTask+CreateComment round-trip;
  in-process, real-broker wire, and subprocess tests cover the round-trip
  and per-capability denial.
- Docs: spec, GRPC-CONTRACT, HOST-DATA-API.proto, proto comments moved
  writes deferred -> implemented; ADR 0043 amended with the concrete
  service-layer routing decision.

* feat(plugins): send a message to a task session via Host SendMessage (replaces CreateComment)

The office TaskComment write was the wrong primitive — it's an office/
dashboard construct, not a way to message the agent working a task, and
it only did anything under office reactivity. Replace the CreateComment
write RPC with SendMessage, which delivers a prompt to a task session
through the orchestrator's real delivery path (the same one message_task
uses).

- Proto: swap CreateComment/Comment for SendMessage(SendMessageRequest)
  returns SendMessageResponse{session_id, status}; regenerated stubs.
- SDK: Host.Comments() removed; Host.Messages().Send(taskID, sessionID,
  text) added (pairs with Messages().List), returning MessageDispatch.
- Gating: api_write:comments dropped; SendMessage gated api_write:messages
  (independent of api_read:messages on the same accessor, like Tasks()).
- Delivery: a new pluginsTaskMessengerAdapter (backendapp) resolves the
  target session (explicit id verified against the task, or the primary
  session), records a user message stamped source="plugin:<id>", then
  dispatches by state — running → queue; idle/completed → prompt (resume
  if the agent process is gone); never-started → launch; failed dispatch
  deletes the recorded message. Wired via SetWriteDeps (live-read).
- Tests: adapter state-machine unit tests (queue/start/prompt/resume/
  delete-on-failure/belongs-to-task/no-primary/terminal); SDK, in-process
  gating, wire, and subprocess round-trips updated to SendMessage.
- Docs: spec, GRPC-CONTRACT, HOST-DATA-API.proto, proto comments, and the
  ADR 0043 amendment updated from comment-create to message-send.

* fix(plugins): address PR review — nil guards, detached contexts, state validation

Follow-up fixes from the #1970 review (Claude + CodeRabbit bots):

- grpcHostServer.CreateTask/UpdateTask/SendMessage: nil-guard the returned
  value before toProto() so a custom/test Host returning (nil, nil) yields a
  gRPC Internal error, not a server panic (matches GetTask's pattern).
- host.go: fix stale server doc comment (Comments()/CreateComment →
  Messages()/SendMessage).
- startTaskBestEffort and the post-resume wait+retry now run on
  context.WithoutCancel(ctx): the task/resume is already committed, so a
  plugin's incoming deadline must not silently abort the launch/resume.
- pluginsTaskWriterAdapter.UpdateTask validates the state string against the
  known task-state enum (excluding orchestrator-owned SCHEDULING) and returns
  InvalidArgument, so a plugin typo can't forward a bogus state to the service.
- Tests: add the resume-wait-timeout path (message deleted so a retry can't
  duplicate), and a dedicated pluginsTaskWriterAdapter test covering
  source→metadata mapping and state validation (both adapters now depend on
  narrow interfaces for testability).

* fix(plugins): launch start_agent asynchronously so CreateTask doesn't block

Review nit follow-up: startTaskBestEffort called StartTask synchronously, so
with the detached context the plugin's CreateTask RPC blocked on the
orchestrator's full inline launch path (office lookup, state update, workflow
step move, task fetch) with no bound — and the "asynchronous" comment was wrong.

Move the fire-and-forget into pluginsTaskStarterAdapter (backendapp, no goleak),
mirroring MCP's launchAutoStartTask: the launch runs in a goroutine on a
context.WithTimeout(context.WithoutCancel(ctx), AgentLaunchTimeout), and
StartTask returns immediately. The plugin host stays a simple synchronous call
(its taskStarter contract now documents "returns promptly, launches async").

Adds adapters_plugin_starter_test.go: launch invoked, returns before the launch
completes, detaches from a cancelled caller context, and swallows launch errors.

* docs(plugins): document write validation + SendMessage rollback; harden starter test cleanup

Addresses the final PR #1970 review nits:
- adapters_plugin_starter_test.go: register the block-channel release via
  t.Cleanup (sync.Once-guarded) before the goroutine can block, per AGENTS.md.
- GRPC-CONTRACT.md: document CreateTask/UpdateTask validation + error rules
  (title required, id required, NotFound on missing task, invalid-state reject).
- spec.md: document that a failed SendMessage dispatch deletes the recorded
  message, plus the required-field/NotFound/terminal-session rules.

João Salavisa 1ba81a7cd0 refactor(plugins): remove the unused tools feature (#1776)
Plugin `tools[]` overlapped with MCP, kandev's established mechanism for
exposing tools to agents (`internal/mcp/`), and the `InvokeTool` path was
never wired into agent tool sets — the `listTools` handler was
listing-only. Rather than maintain a half-built parallel surface, remove
it. If plugins ever contribute agent tools, they should feed through MCP,
not a separate `InvokeTool` RPC.

Removes:
- proto `InvokeTool` RPC + `ToolRequest`/`ToolResponse`/`ToolContext`
  messages (regenerated `*.pb.go` / `*_grpc.pb.go`)
- pkg/pluginsdk `InvokeTool` from the `Plugin` interface and
  `UnimplementedPlugin`, the Tool* Go-native types, and the
  `RemotePlugin`/`GRPCServer` dispatch
- internal/plugins `Service.InvokeTool`, the `listTools` handler +
  `GET /api/plugins/tools` route, `PluginToolDTO`, and the manifest
  `Tools` field + tool-name uniqueness validation
- frontend `PluginTool`/`PluginToolDTO` types, `listPluginTools`, and the
  manifest-card tools list
- fixture/e2e `InvokeTool` echo impl and the `tools:` manifest block

Test doubles that used the "crash" tool to exercise crash-restart now use
a "crash" webhook key instead. Internal specs (GRPC-CONTRACT, spec) drop
the tool RPC/feature; docs/public was already updated in #1774.

João Salavisa e145d48f22 feat: add plugin system with grpc runtime and native ui plugins (#1742)
* feat: add plugin system with grpc runtime and native ui plugins

- go plugin backends ship as release tarballs (per-platform binaries, checksums) that
  kandev installs from url/upload or filesystem sideload+sync, then spawns and
  supervises via hashicorp/go-plugin (unix socket / loopback tcp+automtls)
- strict typed grpc contract (kandev.plugin.v1): DeliverEvent/InvokeTool/HandleWebhook
  plus a capability-gated host service (state, secrets, emit); author sdk in
  pkg/pluginsdk; packaging cli in cmd/plugin-pack
- native frontend bundles: window.registerKandevPlugin + registry/host loader with
  dynamic routes, nav items, slots and ws handlers; plugins settings page with
  install dialog, sync button and enable/disable/uninstall
- gated behind the plugins feature flag (prod off, dev/e2e on); covered by unit and
  integration tests plus playwright e2e against a real packaged fixture plugin

* fix(plugins): hydrate base app context on plugin routes

Plugin-owned SPA routes classify as RouteUnknown, so the boot payload shipped
only feature flags — no workspaces, workflows, or kanban context. Native plugin
UI (e.g. host.ui.TaskCreateDialog) then had an empty store. Hydrate the same
base context as the Home route for unknown SPA routes.

* feat(plugins): expose TaskCreateDialog on host.ui

Lets a native plugin open kandev's real create-task modal (prefilled via
initialValues) instead of POSTing directly.

* fix(plugins): harden filesystem/URL sinks against CodeQL findings

Add sink-level guards on the plugin trust boundary: securejoin containment on
archive extraction (zip-slip), plugin-id validation before every fs_store path,
http/https scheme validation on install-from-URL, and non-interpolated ws-handler
error logging.

* fix(plugins): address review findings (races, resource caps, lifecycle)

- serialize per-plugin startup to close a TOCTOU double-spawn race, and let a
  plugin restart after exhausting attempts
- bound plugin startup with an explicit 30s timeout
- reject backslash paths and cap decompressed bytes by actual size in pkgtar;
  only mark a package Signed when a verifier actually ran and passed
- delete plugin_state on uninstall; validate webhook keys against the manifest
  and cap webhook body size; restart an active plugin when a new version installs

* fix(plugins): sanitize plugin-id path sinks for CodeQL

Pin the plugin id to a single path segment with filepath.Base at recordPath/
configPath and pkgtar.Remove — a barrier the taint analysis recognizes.
Behaviour-identical for valid ids (already validated by safePluginID); clears
the go/path-injection alerts.

* fix(plugins): inline plugin-id validation at path sinks for CodeQL

filepath.Base does not strip '..', so it is not a path-injection barrier. Call
the recognized safePluginID / id-pattern guard inline in Delete/GetConfig/
SetConfig and pkgtar.Remove — the same barrier that already cleared the Get sink.

* fix(plugins): address code-review findings (backend)

- add capability-gating tests for the Host RPC service (was untested)
- close a stop-during-start orphan race so Disable/Uninstall can't leave a
  supervised subprocess behind
- on failed upgrade, remove only the new version dir (not all versions + data);
  restart the prior version
- validate manifest version and reject ids ending in .config (record-file alias)
- make Deliverer.Refresh non-blocking and cancel in-flight delivery on worker stop
- clamp out-of-range webhook status, skip-and-warn corrupt records in List,
  write records atomically, semver-aware sideload version pick

* fix(plugins): address code-review findings (frontend)

- wrap plugin routes + settings routes in a shared PluginErrorBoundary so a
  throwing plugin page shows a fallback instead of white-screening the SPA
- fix disable/re-enable in one session: keep the cached registration and
  re-run initialize instead of relying on a cached ES-module re-import
- prefix root-relative bundle/style URLs with apiBaseUrl (split-origin/Tauri)
- surface partial-install warnings via toast.warning instead of a bare success
- dedupe/remove injected style links on unload; gate PluginNavItems on the flag

* fix(plugins): serialize per-plugin lifecycle + guard config writes

- add a per-plugin keyed lock in Service so concurrent Enable/Disable/Install/
  Uninstall/UpdateConfig for one id are serialized (no status-machine race)
- take s.mu in SetConfig/GetConfig and write config atomically
- bound each plugin initialize() with a timeout so one hung bundle can't stall
  the rest of the boot load

* test(plugins): split service_test.go to satisfy file-length lint

Move the install/URL test group into service_install_test.go; no logic change.

* ci: build and ship the e2e fixture plugin package to E2E shards

The plugin E2E specs' global-setup requires apps/backend/.build/kandev-plugin-e2e-1.0.0.tar.gz.
Build it in the E2E build job, upload it as an artifact, and download it in both
the regular and container shard jobs.
