João Salavisa de92557f46 test(backend): wire goleak goroutine-leak detection across 8 packages (#1139)
* chore(backend): add go.uber.org/goleak test dependency

Promotes the previously-indirect goleak v1.3.0 to a direct require so
per-package TestMain calls can use it for goroutine leak detection.

* fix(backend/lifecycle): drain workspace-stream backoff on Manager.Stop

StreamManager.connectWorkspaceStream slept the full retry backoff in
time.Sleep between failed attempts. SessionTraceContext is deliberately
uncancellable (it carries a long-lived span), so if the Manager began
shutting down mid-backoff the goroutine outlived Stop() and stranded
until the timer fired.

Thread Manager.stopCh through the StreamManager constructor and add a
sleepOrStop helper that selects between the timer and the shutdown
signal. ReconnectAll's startup sleep gets the same treatment.

TestConnectWorkspaceStream_BackoffDrainsOnStop closes stopCh while a
failing-port retry is in flight and asserts the goroutine exits within
500ms — fails without the fix, passes with it.

* fix(backend/github): close sqlite DB in newTestStore to drain connectionOpener

newTestStore opened *sqlx.DB via db.OpenSQLite but never registered a
Close on cleanup, leaving database/sql.(*DB).connectionOpener goroutines
parked across test boundaries. Add t.Cleanup(sqlxDB.Close); goleak's
per-package TestMain (added in a follow-up commit) is the regression
check.

* test(backend): wire goleak.VerifyTestMain across leak-prone packages

Per-package TestMain in:
- internal/integrations/healthpoll (auth-health ticker loop)
- internal/jira, internal/linear (auth + issue-watch loops)
- internal/github (PR / review / issue poller loops)
- internal/gateway/websocket (per-conn pumps + terminal bridge)
- internal/orchestrator (detached event-handler goroutines)
- internal/agent/runtime/lifecycle (remote-status loop, StreamManager
  helpers; ignores OTel batch-span processor and OTLP retry helper —
  initialised early in the process and only exit on shutdown)
- internal/agentctl/server/process (extends the existing fixture-binary
  TestMain so subprocess + PTY pump leaks surface there)

Catches regressions where a Start/Stop forgets to drain on WaitGroup,
or a detached goroutine forgets to honour ctx/stopCh cancellation.

* docs(backend): document goroutine ownership and leak-testing convention

New "Goroutine ownership and leak testing" subsection under Conventions
in apps/backend/AGENTS.md (CLAUDE.md symlinks to it). Covers:

- Lifecycle: Start/Stop + WaitGroup, both idempotent.
- Cancellation: every long wait selects on ctx.Done() or stopCh; never
  time.Sleep in retry loops (reference lifecycle.StreamManager.sleepOrStop).
- Detached helpers: must respect the owning type's shutdown signal.
- Leak testing: new packages spawning goroutines add goleak.VerifyTestMain;
  IgnoreTopFunction is reserved for genuine third-party background
  goroutines and must carry a comment explaining the suppression.

Lists the packages currently instrumented so future contributors can
mirror the pattern.

* chore(backend/lifecycle): drop dead OTel IgnoreTopFunction from goleak setup

Review follow-up. agentctl/tracing.initTracing only spawns the OTel SDK
provider when OTEL_EXPORTER_OTLP_ENDPOINT is set; in tests it isn't, so
the noop provider is used and no batchSpanProcessor / OTLP retry
goroutines ever exist. The IgnoreTopFunction calls were dead
suppressions and the comment ("called by NewManager via the agent
execution trace path") misdescribed when the SDK init runs. Drop the
ignores and correct AGENTS.md to stop citing OTel as the canonical
suppression example.

* test(backend/lifecycle): drop unneeded 50ms sleep from backoff-drain test

QA follow-up. The 50ms time.Sleep before close(stopCh) in
TestConnectWorkspaceStream_BackoffDrainsOnStop was meant to ensure the
goroutine had entered the backoff sleep before shutdown — but that
ordering doesn't affect the test outcome:

  - With the fix: sleepOrStop sees stopCh already closed and returns
    false on the first call, so the goroutine drains within one attempt
    regardless of when stopCh closes.
  - Without the fix: time.Sleep ignores stopCh, the goroutine burns
    its full 5-retry backoff (~31s), and the 500ms timeout fires.

Removing the sleep makes the test ~12x faster (15ms vs 200ms total) and
removes the only time.Sleep-based wait from the new tests, aligning
with the codebase's "channel-based sync, no sleep waits" convention.
Verified by 50x -race and 5x revert-and-fail.

* fix(backend/github): drain HTTP idle conns before goleak inspects

CI surfaced a leaked goroutine on the Linux runner that local runs
missed: a single net/http.(*http2ClientConn).readLoop parked on a
TLS read, created by net/http.(*http2Transport).newClientConn. The
package's anonymousHTTPClient and PATClient's rewriteTransport both
route through http.DefaultTransport's connection pool, so an idle
HTTP/2 connection in that pool keeps the reader goroutine alive past
m.Run() — invisible on sandboxed local runs where outbound network
is blocked.

Replace github/goleak_test.go's plain VerifyTestMain with an
expanded TestMain that drains http.DefaultTransport's idle
connections before goleak.Find runs. This is the stdlib's
documented teardown for the connection pool, keeps the assertion
strict (no IgnoreTopFunction), and doesn't leak into production
code. Other in-scope packages don't need this — they don't use
http.DefaultTransport for HTTPS calls.

* fix(backend): drain ws.Done on stopCh; always run goleak in github tests

- lifecycle/streams.go: replace bare <-ws.Done() with a select that also
  watches sm.stopCh so a connected goroutine drains when Manager.Stop()
  fires before the remote WS closes. A nil stopCh (isolated tests) blocks
  the nil channel case forever, degrading to plain <-ws.Done() semantics.
- github/goleak_test.go: remove the exitCode==0 guard around goleak.Find
  so leaks are always surfaced even when a test has already failed; original
  exit code is preserved (leaks only promote it to 1).

* fix(backend/lifecycle): close ws on stopCh so agentctl WS loops drain

cubic flagged that the previous shutdown path observed stopCh but never
called ws.Close(), so the underlying WebSocket and its agentctl-side
read/write goroutines (workspace_stream.go:67-68) kept running past
Manager.Stop(). ClearWorkspaceStream only removes the WS from the
execution's tracking — it doesn't close the connection.

Call ws.Close() on the stopCh path. ws.Close is idempotent via
closeOnce, so it's safe even if the remote end already closed.

TestConnectWorkspaceStream_ClosesWSOnStop connects to a mock workspace
server that stays open until the client closes its side; after stopCh
fires, the test asserts ws.Done() closes within 500ms — which is only
true if connectWorkspaceStream invoked ws.Close(). Verified to fail
without the fix and pass with it.

* test(backend/lifecycle): use channel sync instead of sleep polling in ws-close test

cubic flagged that TestConnectWorkspaceStream_ClosesWSOnStop polled
execution.GetWorkspaceStream() in a 500ms sleep loop, which is brittle
under CI load. connectWorkspaceStream already accepts a ready
channel that closes after SetWorkspaceStream — pass it in and wait on
the channel instead.

synctest isn't viable here (real network I/O), so channel-based sync is
the testing convention per AGENTS.md.
