Integrate chat recovery, chronological history and shortcut help

[Chris0Jeky]

This integration brings three independently reviewed milestone fixes onto the delivered Review/capture baseline: shortcut help follows feature availability and uses translated labels; chat keeps successful submissions visible through failed refreshes and provides explicit board-load retry; every chat consumer receives chronological history.

Preserves the commits from #2827 (aaa510b), #2828 (040c94d), and #2829 (fe4cf5c). Refs #1968, #2004, #2235. No parent issue completion claim.

Qualified candidate: 3923500 against 06bd4d1. Fifteen changed files, three conflict-free merge commits, no manual resolution edits.

Validation:

• Full frontend: 393 files, 6243 passed / 3 skipped, exit 0.
• Typecheck, build, nine-file scoped ESLint, diff check passed; doc links 674 files / 0 broken.
• Chromium SC-005 passed using a fresh synthetic Mock database: link an unbound chat, explicitly continue its retained instruction, reach Review, and verify no board mutation.
• Full backend: dotnet test backend/Taskdeck.sln -c Release -m:1: 9096 passed / 5 skipped, exit 0 (Domain1637, Application4245, API2907, CLI243, Architecture28, Integration36)..
• Fresh independent Terra integration review: SHIP. All source heads and exact changed-file contents preserved; no hidden merge edits or causal HIGH/CRITICAL interaction found. Each source also had a fresh independent review.

Limits and follow-ups:

• The browser run proves the ordinary explicit continuation flow; failed-refresh cases are covered by focused unit tests, not browser fault injection. No live provider was used.
• Accepted MEDIUM chat recovery cases remain tracked on Automation Chat produces prose, never proposals — the chat workflow needs re-thinking #2004: stale local fallback duplication after bind and another failed refresh (comment5602524172), and cached board choices hidden until a failed reload is retried (comment5602618974). Neither resends a server action or bypasses authority.
• Existing compiler/build warnings remain. Canonical STATUS/MASTERPLAN and OUTSTANDING_TASKS.md are unchanged; this coordinator's local checkpoint records qualification. Human decisions and parked Scope Review refresh health and preserve retained warnings #2823/Integrate transcript corrections and Review feedback repairs #2824 remain outside this candidate.

Coordinator cleanup: local and remote39235004b8f8ca7612d7f23969756afb30945e6b agreed, tracked tree clean, no worktree node/dotnet/testhost process remained. Ignored inventory was .tmp, backend bin/obj, frontend dist/node_modules and test-results. Copied all .tmp logs, synthetic Mock database and review diff OUT to .claude/local/milestone-20260909/preserved-2830/runtime-and-verification; copied test-results alongside it. Disposable generated/install trees required no preservation. Plain git worktree remove succeeded; remote branch/source commits preserved. Full backend session84117 completed exit0 with9096passed5skipped; logs preserved. Primary remains unchanged with its original two untracked directories. Hosted CI is pending; no merge claim.
