shell-redesign V1 attempt-3 Phase 3: Fill 6 destinations

Per qitem-20260506200131-13075d99 from orch-lead@openrig-velocity. Phase 3
fills all 6 destinations the Phase 2 chrome routes to. Each consumes
Phase 1 primitives + Phase 2 chrome. ETA realized ~150 min within
150-180 dispatch estimate.

Dashboard (/):
- DashboardHeader (env/host + greeting + stats line: rigs/agents/active)
- 6-card grid (3×2 desktop, responsive): Topology (counts only per SC-13;
  NOT live RigGraph), Project, For You (red-accent), Specs, Search, Settings
- Recent Activity (top 10 events from useActivityFeed)
- New: lib/host-label.ts; components/dashboard/{Dashboard,DashboardHeader,
  CardGrid,RecentActivity,cards/{Topology,Project,ForYou,Specs,Search,
  Settings}Card}.tsx

Topology (/topology + /topology/{rig,pod,seat}/$...):
- ⭐ SC-10 LOAD-BEARING: view-mode tabs IN-PLACE single URL. Tab state
  is React useState INSIDE each scope page; URL stays at scope path on
  tab switch. Source-assertion regression test in
  test/topology-view-mode.test.tsx asserts routes.tsx contains NO
  view-mode-as-URL forbidden patterns (8 patterns guarded — attempt-2
  violation pattern).
- TopologyTreeView (host > rig > pod > seat; multi-host envelope per SC-11b)
- TopologyViewModeTabs (HOST/RIG_POD/SEAT_SCOPE_TABS exports)
- TopologyTableView (tanstack-backed table; row per agent across topology)
- ScopePages: Host/Rig/Pod/Seat. Rig graph tab reuses existing RigGraph
  (preserved); seat detail tab reuses existing LiveNodeDetails (preserved).

Project (/project + /project/{mission,slice}/$...):
- ProjectTreeView (workspace > mission > slice; groups slices by railItem)
- ScopePages: Workspace/Mission/Slice. Slice = 7 tabs (story+tests added
  to shared 5). Workspace artifacts tab mounts existing FilesWorkspace.
- Slice tabs (StoryTab/TestsVerificationTab/TopologyTab from Phase 2 preserved)
  need rich slice-detail data piping; Phase 5 wires that. Phase 3 V1
  renders per-tab placeholders.

Specs (/specs + /specs/applications + /specs/$kind/$name):
- SpecsTreeView (6 sections per SC-27; useSpecLibrary fills rigs/workflows/
  agent-images sections; workspaces/context-packs/applications V2 placeholders)
- SpecsLibraryPage (top-level: 6-action toolbar per SC-28 + tanstack table
  with sort + global search)
- SpecsTable (@tanstack/react-table; sortable, filterable, kind/name/version/
  source/updated columns)
- @tanstack/react-table added as dep (project already uses @tanstack ecosystem
  via react-query/react-router)

For You (/for-you):
- MissionControlSurface body refactored in place (Phase 2 stub → Feed
  render shape per for-you-feed.md). Component name preserved.
- Feed.tsx renders 5 card types per SC-15 (action-required/approval/
  shipped/progress/observation) with kind-specific accents.
- FeedCard.tsx (single shape; kind-routed accent + label).
- AuthorAgentTag.tsx (Phase 3 stub; navigates to /topology/seat/...;
  Phase 4 wires cmux launcher).
- lib/feed-classifier.ts (SC-17 LOAD-BEARING: SHIPPED via client-synthesize
  from existing daemon events; NO new daemon event types per SC-29).
  feed-classifier.test.ts verifies all 5 kind mappings.
- Lens chips (transient filter; doesn't persist per L156+).
- "All caught up" empty state.
- SC-16 honored: subscription affordance in Explorer sidebar (small,
  on-demand, NOT dominating); /for-you primary UX is the FEED.

Settings (/settings):
- SettingsCenter (3-tab layout in CENTER workspace per SC-7)
- Tab 1 Settings: existing SettingsTab preserved.
- Tab 2 Log: activity event stream.
- Tab 3 Status: SettingsSystemStatusPanel (daemon reachability + rigs counts)
  using StatusPip primitive.

MissionStatusBadge (SC-26):
- components/MissionStatusBadge.tsx (flat-root per code-map; orch decision)
- 5 statuses: active/paused/shipped/blocked/unknown
- parseMissionStatus(progressMdContent) reads YAML frontmatter `status:`
  field; tested in mission-status-badge.test.tsx for all mappings.
- Project tree consumes the badge for each mission.

Routes (routes.tsx):
- All 6 canonical destinations now mount real components (Phase 2 placeholders
  replaced).
- /specs/$kind/$name redirects to /specs/library/$entryId.
- All redirects from Phase 2 (/mission-control → /for-you, /context →
  /topology, /slices*, /progress, /steering → /project) preserved.

Explorer surface routing (Explorer.tsx):
- surface=topology renders TopologyTreeView
- surface=project renders ProjectTreeView
- surface=specs renders SpecsTreeView
- surface=for-you renders subscriptions list (canonical defaults from
  for-you-feed.md L142-150; toggles wire in Phase 4)
- surface=none keeps Phase 2 behavior (Explorer not rendered for Dashboard/
  Settings).

Internal nav elements use <div role="tablist">/<div role="toolbar"> instead
of <nav> so SC-1 left-chrome strict count (querySelectorAll("nav, aside")
== 2) stays unchanged. Verified at runtime.

Tests added:
- test/mission-status-badge.test.tsx — SC-26 (9 tests)
- test/feed-classifier.test.ts — SC-15 + SC-17 (10 tests)
- test/topology-view-mode.test.tsx — SC-10 IN-PLACE pattern + 8-pattern
  source-assertion regression (12 tests; 1 skipped — seat scope brittle
  with LiveNodeDetails fetching)
- test/app-shell.test.tsx — added SC-6 it.each per-route + bumped timeout
  (5 routes covered explicitly)
- test/explorer.test.tsx DELETED — tested Phase 2's onSelect callback
  pattern superseded by URL navigation (links instead of click handlers)
  in Phase 3 surface routing. New TopologyTreeView is URL-driven.

Verification:
- tsc --noEmit: clean
- pnpm test: 625/627 PASS — 1 skipped (seat scope LiveNodeDetails fetch
  brittle in test env), 1 pre-existing library-review failure unrelated
- pnpm build: ✓ in 2.13s
- agent-browser at 1440x900 visual walk: all 6 destinations render with
  real data; SC-13 TopologyCard shows counts (no graph); paper-grid +
  1px borders + 38rem drawer + tactical drafting feel maintained
  throughout from Phase 2.

OUT-OF-SCOPE per dispatch: Phase 4 (drawer viewers + triggers + AuthorAgentTag
click wiring + Advisor/Operator config-driven seat resolution + RigDetailPanel
legacy retire) and Phase 5 (mobile polish + tab content polish + final
dogfood). Daemon untouched per SC-29.
