Kandev Agent c53f699714 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

Title

A standalone git repo implementing a complete native-UI kandev plugin, usable as the reference/import example.

Inputs

PLUGIN-API.md (frontend contract + "Example plugin must") and the manifest format (spec + task-16 ui.bundle).
The plugin is a separate process + its own git repo. Create it OUTSIDE the kandev repo at /home/jcfs/.kandev/tasks/kandev-plugin-system_t6e/kandev-plugin-hello/ and git init it (do not nest inside kandev's git). Also drop a copy/symlink note in kandev docs pointing to it.

Acceptance

Repo kandev-plugin-hello/ with git init + initial commit:
- manifest.yaml: id kandev-plugin-hello, api_version 1, base_url http://localhost:9100, endpoints (health/events/tools/webhooks), ui.bundle: /ui/bundle.js, capabilities.events ["task.created"], one tool echo, config_schema minimal.
- server/ a small stdlib-only Go HTTP server (or Node) serving: /health, /events (HMAC verify, logs), /tools/echo, /webhooks/*, and /ui/bundle.js (the built ES module) + any /ui/* assets.
- ui/ source for the bundle: an ES module that calls window.registerKandevPlugin("kandev-plugin-hello", { initialize(registry, host) {...} }) and registers: nav item "Hello" → route /plugins/hello (a native page using host.jsx + host.ui showing a task-created counter), a task-sidebar slot component, and a registerWsHandler("task.created", ...) incrementing the counter. No bundled React (uses host.React). Provide a tiny build (esbuild) producing server/public/ui/bundle.js, or hand-write the bundle as plain JS using host.jsx so no build step is needed (prefer no-build for portability).
- README.md: what it demonstrates, how to run the server, how to register it against a running kandev (POST /api/plugins/register with manifest, or via the Plugins settings page), and how the bundle loads.
- Makefile/run.sh to build+run.
Manually loadable: running the server + registering the manifest makes the "Hello" nav item and /plugins/hello page appear in kandev (verified by task-22 e2e).

Files

new repo at /home/jcfs/.kandev/tasks/kandev-plugin-system_t6e/kandev-plugin-hello/**
docs/public/ or docs/ pointer in kandev (a short "example plugin" note)

Verification

Build the bundle (if a build step) and go build/node -c the server.
curl /health, curl /ui/bundle.js return 200; bundle is a valid ES module that references window.registerKandevPlugin.

Output contract

Report repo path, files, whether a build step is needed, and the exact registration command. This repo is a deliverable the user asked for explicitly.

Dependencies

task-16 (manifest bundle field) + PLUGIN-API.md.
