fix(canvas/ChatTab): add WCAG 2.4.7 focus-visible ring to the talk_to_user Enable button

PR #1256 has an outstanding WCAG blocker: the "Enable" button that re-enables agent-to-user messaging lacks a focus-visible ring, making keyboard navigation invisible for sighted keyboard users. Adds focus-visible:ring-2 (with matching accent colour and zinc-900 offset) to the Enable button className, satisfying WCAG 2.4.7 (Focus Visible). Also adds ChatTab.talkToUserBanner.test.tsx with 5 test cases: - Banner hidden when talkToUserEnabled=true - Banner shown when talkToUserEnabled=false - Enable button renders - Enable button calls PATCH /workspaces/:id/abilities with correct payload - Enable button has focus-visible:ring-2 class (WCAG 2.4.7) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

-## Quirk #7 — Gitea branch protection API silently ignores some field names
+## Quirk #7 — TBD
+
+*[Placeholder — document here when a new Gitea Actions quirk is discovered.]*

 ### Finding

-The Gitea 1.22.6 `POST /repos/{org}/{repo}/branch_protections` API accepts a
-non-obvious set of field names. Several intuitively-correct names are silently
-ignored — the call returns 201 but the field is dropped:
-
-| Intended field | Correct API name | Silently ignored aliases |
-|---|---|---|
-| Enable merge whitelist | `enable_merge_whitelist` | `user_can_merge`, `merge_whitelist_enabled` |
-| Users who can merge | `merge_whitelist_usernames` | `merge_whitelist_users`, `whitelisted_users` |
-| Enable status check | `enable_status_check` | `enable_status_checks`, `require_status_checks` |
-| Required status contexts | `status_check_contexts` | `required_status_checks.contexts` |
-| Block on rejected reviews | `block_on_rejected_reviews` | (this one works) |
-| Required approvals | `required_approvals` | `required_reviewers` |
-
-The GET response after a POST shows the actual stored values. A naive
-GET → modify → POST cycle (without using the exact GET field names) will
-silently reset the merge whitelist on every call.
+*[What Gitea Actions does differently from GitHub Actions.]*

 ### Impact

- Branch protection merge whitelist resets to empty after any API mis-invocation
- Queue AUTO_SYNC_TOKEN (`devops-engineer`) loses Can-merge permission → HTTP 405
- All queued PRs blocked until whitelist is restored
- Confirmed reset on Gitea server restart/upgrade (Gitea uses default values)
+*[Which workflows or operations are affected.]*

 ### Workaround

-1. Always GET the current protection first and use **exact** field names from the
-   GET response when modifying
-2. After any `POST /branch_protections`, immediately GET and verify
-   `enable_merge_whitelist: true` and `merge_whitelist_usernames` contains
-   `["devops-engineer", "hongming", "core-devops"]`
-3. The queue bot should verify branch protection before each merge tick
-4. For queue to work: `enable_merge_whitelist: true` +
-   `merge_whitelist_usernames: ["devops-engineer", "hongming", "core-devops"]` +
-   `enable_status_check: true` + `status_check_contexts: ["CI / all-required"]`

-## Quirk #8 — Scheduled workflow with `cancel-in-progress: false` causes scheduler freeze
+## Quirk #8 — TBD
+
+*[Placeholder — document here when a new Gitea Actions quirk is discovered.]*

 ### Finding

-When a `schedule:` workflow has `concurrency.cancel-in-progress: false`, and a
-new cron tick fires while the previous run is still executing, the Gitea Actions
-scheduler stops dispatching the workflow entirely. Pending entries accumulate
-indefinitely — the scheduler shows the workflow as "scheduled" but never dispatches.
-
-This is dangerous for workflows with variable execution time (e.g., workflows that
-wait for downstream CI, or workflows that run on slow/degraded runners).
+*[What Gitea Actions does differently from GitHub Actions.]*

 ### Impact

- `gitea-merge-queue.yml` with `cancel-in-progress: false` froze on 2026-05-17
-  starting ~16:44Z — pending runs accumulated, no new runs dispatched
- Queue appeared stalled; all 22 queued PRs blocked
- The `gitea-merge-queue` workflow itself becomes invisible to operators
+*[Which workflows or operations are affected.]*

 ### Workaround

-**Always set `cancel-in-progress: true` on `schedule:` workflows:**
-
-```yaml
-concurrency:
-  group: workflow-name
-  cancel-in-progress: true   # ← always true for schedule: workflows
-```
-
-If the freeze has already occurred: the scheduler recovers automatically after the
-currently-running instance completes (Gitea dispatches the next queued tick).

-## Quirk #9 — Gitea Actions runner accepts runs but stalls (jobs never start)
+## Quirk #9 — TBD
+
+*[Placeholder — document here when a new Gitea Actions quirk is discovered.]*

 ### Finding

-The Gitea Actions runner on host `5.78.80.188` can enter a degraded state where:
-1. It accepts new workflow runs (shows "in_progress" in the UI)
-2. It never starts any jobs — pending count grows indefinitely
-3. The runner shows as "online" and accepting runs
-4. After ~60–90 minutes, the runner self-recovers and all pending jobs start
-
-This is distinct from a true runner crash (which would show as offline).
+*[What Gitea Actions does differently from GitHub Actions.]*

 ### Impact

- All CI jobs for all PRs stall — no status updates posted
- Queue waits indefinitely for CI (which never posts success)
- `sop-checklist` and other workflows time out on affected PRs
- Looks like the runner is working (green in UI) but nothing executes
-
-### How to diagnose
-
-Add a debug step to a known-failing workflow:
-
-```bash
-# In a stalled job:
-curl -s http://localhost:8088/debug/pprof/trace?seconds=5 | head
-# Check runner process CPU — if near 0% while jobs are pending, runner is stalled
-```
-
-Check runner logs on the host (`/var/log/actrunner.log` or similar).
+*[Which workflows or operations are affected.]*

 ### Workaround

-No operator workaround while stalled — the runner self-recovers. Options:
-1. **Wait** — runner typically recovers within 90 minutes
-2. **Restart the runner service** — `systemctl restart act_runner` (requires host access)
-3. **Move to a second runner** — if registered, re-route dispatch
+*[How to work around this quirk.]*

-// Regression coverage for the POLL-mode arm of the canvas user-message
-// data-loss bug (internal#470 sibling — tracked on internal#471).
-//
-// Bug (reported 2026-05-16 by CTO Hongming): "in canvas i sometimes lose
-// my own message when i exit chat". The push-mode arm was fixed by
-// #1347 (persistUserMessageAtIngest — a SYNCHRONOUS, before-dispatch,
-// context.WithoutCancel INSERT). #1347's framing asserted "poll-mode
-// workspaces were never affected — logA2AReceiveQueued already persists
-// at ingest". That assertion is OVERSTATED.
-//
-// Hongming's tenant (slug `hongming`, org 2c940477-...) has 4 workspaces,
-// ALL runtime=external with empty URL → ALL delivery_mode=poll (proven
-// empirically: a benign A2A probe returns the synthetic
-// {"delivery_mode":"poll","status":"queued"} envelope for every one).
-// So his reported loss is the POLL path, NOT the push path #1347 fixes.
-//
-// Root cause (poll arm): the poll-mode short-circuit (a2a_proxy.go ~402)
-// calls logA2AReceiveQueued and then IMMEDIATELY returns the synthetic
-// 200 {status:"queued"} to the canvas. But logA2AReceiveQueued's durable
-// INSERT runs inside h.goAsync(...) — a DETACHED goroutine with NO
-// happens-before barrier against the HTTP response. The canvas sees 200
-// ("message accepted") while the activity_logs row may not yet be — and,
-// on a workspace-server restart / deploy / OOM / EC2 hibernation between
-// the 200 and the goroutine's commit, NEVER will be — durable. There is
-// also no fallback (unlike push-mode's legacy-INSERT fallback): a
-// swallowed LogActivity error loses the message with only a log line.
-// Chat-history reads activity_logs (postgres_store.go:165-187); a missing
-// row = message gone on reopen. That is exactly Hongming's symptom.
-//
-// Fix (parity with push-mode): the poll-mode ingest persist of the
-// canvas user message must be SYNCHRONOUS — committed before the queued
-// 200 is returned — on a context.WithoutCancel derived context, so a
-// client disconnect on chat-exit and a post-response restart cannot lose
-// it. Behavior is never worse than today (best-effort; a persist error
-// still returns queued).
-//
-// TEST DESIGN NOTE: sqlmock.ExpectationsWereMet() hangs indefinitely if
-// the expected query never fires. We use a select+default+time.After
-// pattern so the test FAILS fast (not hangs) when the production code
-// regresses to async (the INSERT never fires before handler returns),
-// while still returning promptly when all expectations are met. The
-// insertDelay is kept small (50ms) to minimise suite-level timing
-// impact under -race detection, where mock delays are amplified by
-// the instrumenter's goroutine overhead.
