feat(v0.7): Walk-away Workbench (Band A + B) — multi-agent parallel build
Implements docs/PLAN_WALKAWAY_WORKBENCH.md (27 tasks, waves R0→W0→W1×14→W2→W3→W4)
via module-builder agents. 23 tasks built, 0 blocked.
Band A (finish the walk-away loop): A1 Web Push + lock-screen approve/deny
(web-push dep), A2 voice dictation, A3 quick-reply chips + saved-prompt palette,
A4 activity timeline, A5 stuck/idle alert.
Band B (workbench above the terminal): B1 read-only git diff viewer, B2 statusLine
telemetry → per-tab cost/context/PR gauges, B3 create git worktrees from the UI,
B4 plan-mode / permission-mode relay.
New: src/push/* (subscription store + VAPID push), src/http/{diff,statusline}.ts,
src/session/timeline.ts, public/{diff,timeline,quickreply,push-ui,...}.ts, sw-push,
statusLine script; extends hook intake, manager, server routes (Origin/CSRF guards
+ per-IP rate limits on state-changing ones; loopback-only ingest), terminal-session,
tabs, projects detail, service worker, setup-hooks (statusLine + ntfy bridge).
Orchestrator reconciled a W0 contract gap: added the 21 v0.7 Config fields to the
Config interface in types.ts (T-types had left them only in config.ts's return).
Verified: both tsc clean, full vitest + coverage 91.4/84.1/92.2/93.4 (≥80×4),
build:web OK. W4 review: no CRITICAL/HIGH; all security checks pass. Follow-ups
(non-blocking): move approve.mode validation into parseClientMessage, drop CSP
ws:/wss: wildcard, validate worktree base ref, +2 targeted tests.
