docs(ai): refresh handoff for compute swap

- HANDOFF: rewritten resume point. First action on resume is `git push`
  (commits 0f00ee5 and 665530f are local-only). Visual QA + bug bash is
  the active work; 4 plan-locked items + the structural task-lane fix
  all need real-browser verification.
- CURRENT_TASK: add 0f00ee5 and 665530f to the commit table; reframe
  "Just shipped" as a per-commit summary; flag the task-lane fix as
  needing visual confirmation.
- SESSION_LOG: chronological entry for this session with full detail
  (audit, four polish items, race-condition wiring, structural
  task-lane fix, test status, files touched).
- DECISIONS: new entry "Tag the task-lane state with an owner chatId"
  documenting the structural pattern, what was rejected, and the
  forward implication that future task-lane state slices follow the
  same owner-tagging pattern.

 **Test status:** full backend suite → `1103 passed in 259.63s` with `-n auto` after the unification. Frontend `tsc -b` clean. End-to-end smoke test against the running dev stack confirmed: SSE handshake delivers `ready` + `handoff_created` frames; `listHandoffs` returns the unclaimed handoff for a senior pre-claim; `claimHandoff` flips session status `escalated` → `active`; senior (non-owner, non-target) can `GET` an in-transit session detail; **a single legacy `/escalate` call now produces status='escalated', SessionDocumentation, SessionHandoff row, AppNotification with link `/pilot/{id}?pickup=true` for the team admin, and a PSA push attempt** — all from one funneled HandoffManager call. Branch pushed; draft PR #155 open.

+**Commit `0f00ee5`** — four plan-locked wedge polish items:
 
 - **Live AI assessment refresh on the magic-moment screen.** New `HandoffAssessmentReadyEvent` type + `onAssessmentReady` handler on `streamEscalations`. `AssistantChatPage` opens a scoped SSE subscription whenever it has a tracked handoff with no AI assessment yet; on a matching event it refetches and replaces both `magicHandoff` and `overlayHandoff` in place. Closes the loop on the async-assessment commit `e8ba74e`.
 - **Suggested-step chips below the chat input.** New `chipsHidden` state in `AssistantChatPage` defaulting to false; a chip strip renders above the composer when `magicHandoff?.ai_assessment_data?.suggested_steps[]` is non-empty and the magic-moment has dissolved. Click prefills input + focus; first send hides the strip; explicit X also hides. Per-session lifetime (Codex correction locked design).
 - **Unread 6px dot on `EscalationQueue` cards.** localStorage-persisted seen set (`rf-escalation-seen`, capped 200). Dot renders top-right of any card not yet seen. Cleared on **open (card click) or claim (Pick Up)** — NOT on hover (Codex correction). Pick Up onClick now stops propagation so the wrapper's open handler isn't double-fired.
 - **Race-condition toast on claim conflict.** New `HandoffAlreadyClaimedError` exception class in `handoff_manager.py`. `claim_session` now eager-loads `claimed_by_user`, rejects different-user re-claims (idempotent for same-user), and raises with the winner's id/name/timestamp. Endpoint translates to 409 with structured detail. `AssistantChatPage.handleStartHere` extracts the detail, formats `"Already claimed by {name} {time_ago}."` via `timeAgo()`, drops `?pickup=true`, and dismisses the magic-moment so the loser flows back to the queue. Backed by 2 new unit tests in `test_handoff_manager.py`.
 
+**Commit `665530f`** — structural fix for the recurring stale-task-lane bug. Owner-tagging pattern applied to `activeQuestions` / `activeActions` / `showTaskLane`. See [`DECISIONS.md`](DECISIONS.md) for the architecture write-up. **User-reported on next session: needs visual verification.**

 ## Two-metric framing — read this before quoting numbers to anyone
 
 The in-product endpoint measures *post-claim time-to-first-action*. The "minutes recovered" sales claim is `manual_baseline − in_product_metric`. Manual baseline comes from the founder's stopwatch on the next 5 escalations (The Assignment in the design doc). Don't roll the in-product number alone into "minutes recovered" — that's the apples-to-oranges miscount Codex caught.
