Wire TUI and exec Auto Review lifecycle events into durable state

[shiny-code-bot]

Summary

Wire the existing Auto Review producers/observers into the durable store from #325.

Scope

• TUI run_background_review records run creation, snapshot, agent attachment, worktree, and completion.
• Exec AutoReviewTracker records completions and status into the same repo-scoped store.
• Agent status/progress updates refresh last_activity_at for Auto Review runs.
• Replace TUI-only recovery assumptions with store-backed activity/currentness where possible.

Acceptance Criteria

• TUI launch/start/finish paths update durable run state.
• Exec Auto Review completions update durable run state.
• Activity is based on agent/progress events, not elapsed runtime alone.
• Tests cover TUI and exec paths writing compatible run records.

Relationships

Parent: #324
Depends on: #325

Finish Line

TUI background Auto Review, exec AutoReviewTracker, and AgentManager status updates record lifecycle transitions and activity heartbeats into the durable AutoReviewRun store.

Completed in PR #333: #333

Landed durable lifecycle wiring for Auto Review:

• TUI launch/start/status/skip/stale-loss/completion persistence.
• Exec agent-status lifecycle persistence with restart row reuse by agent id.
• Startup reconciliation of orphaned in-flight runs.
• Structured output sidecars where parseable, heuristic summary/finding counts otherwise.
• Bounded finding digests for future low-token ledger use.

Validation:

• cargo test -p code-core review_store
• ./build-fast.sh
• git diff --check
