Announce unavailable Review results without moving focus

[Chris0Jeky]

A delayed unavailable-proposal lookup can preserve focus in the queue or a batch approval dialog but settle silently. Add a persistent polite status region using the existing localized unavailable/malformed message and return action. Capture which surface owns the result so the modal announces inside its own subtree, polling does not repeat it, and cancelling the dialog does not replay it in the queue.

Verification:

• Baseline: two new announcement expectations failed; four existing focus cases passed. Fixed focused mounted/dialog coverage:9passed.
• Full frontend run:6287passed/3skipped/2failed. The two failures were existing exact-child-list expectations missing the added status node. A test-only follow-up updates those lists and verifies the node remains outside grid flow; all223 tests in the affected three specs then passed. No production logic changed after independent review or browser proof.
• Typecheck, scoped ESLint and production build passed. Synthetic Chromium delayed-lookup check passed1/1 (30.5s), using isolated ports5551/5851 and Mock provider; screenshot inspected. It verifies the persistent status text, preserved focus, and clearing on Return.
• Independent Terra high review: SHIP, no HIGH/CRITICAL blocker. Hosted CI must qualify the final head.

This proves DOM live-region semantics and focus behavior; no actual screen-reader announcement or subjective AT acceptance is claimed. Review-first actions and authorization are unchanged.

Independent Terra high review: SHIP, no causal HIGH/CRITICAL blocker. Each result retains one announcement owner; a fresh lookup clears it, polling the same unavailable ID does not repeat it, and cancelling an owning batch dialog leaves the root status silent. Reviewer did not run tests. The later538fd3cf3 commit changes only two structural test expectations for the added node; affected specs passed223/223, and final typecheck/scoped lint passed.

Synthetic Chromium passed1/1 on the unchanged production implementation, screenshot inspected. Full pre-test-fix suite had6287pass/3skip/2 structural-expectation failures; the scoped pass resolves those two, without claiming a second full run. Hosted required34415015951 is running at final538fd3cf370d2a408729c8954e8e2835d5576d73.

Sixteen evidence files (logs, synthetic database, browser result/screenshot) were copied and hash-verified to .claude/local/milestone-20260909/preserved-2215-announcement before plain worktree removal. Both owned browser ports are closed; all owned test sessions are terminal. No actual screen-reader output was verified. OUTSTANDING_TASKS.md remains unchanged.
