feat: add Project Sentinel supervisory infra, Agentic Sentinality system, and Beta Tracker frontend

## Backend
- **Project Sentinel** (Plan A): sentinel-agent.sh CLI, JulesWebhookBroadcaster WS auth +
  tag-based filtering, JulesOverseer /ingest + doom-loop detection + clarification handler,
  babysitter callbacks in JulesService/StitchService, sentinel REST API routes
- **Agentic Sentinality** (Plan B): 10 Drizzle learning schema tables (sessions, threads,
  messages, enrichment, tags, AI insights, PR reflections), LearningAgent DO with
  contemplation gate (Vectorize + D1 dual-check), LearningWorkflow (4-step CF Workflow),
  /api/learning + /api/governance routes, Active PR Interceptor (sentinel-handler.ts),
  AgentStubs for 11 production DO classes
- **TS fixes**: setState→setStatus, removed generic type params, added getAgentByName util,
  streamTextAgent/createRunner exports, @ts-nocheck on backup file, MCP signature fixes,
  null guards on env secrets
- **wrangler.jsonc**: fixed D1 DB IDs to match production, consolidated DO migrations to
  single v1, added sentinel-patterns Vectorize index, LearningWorkflow binding, cron trigger
- **env-augments.d.ts**: VECTORIZE_INDEX, LEARNING_WORKFLOW, LEARNING_AGENT bindings

## Frontend
- **Beta Tracker** (Linear/ClickUp-inspired):
  - TrackerLayout: left sidebar (views + status counts + saved searches), top toolbar
    (search/filter/new task), AI assistant sheet
  - TrackerListView: hierarchical list grouped by status, checkboxes, inline tagging,
    floating bulk action bar
  - TrackerBoardView: @dnd-kit kanban with 5 columns (Backlog→Done), drag-and-drop
  - TrackerReportsView: recharts analytics (pie + bar), metric cards, team workload,
    AI insights alert
  - TrackerBeta page wrapper: react-query data fetching from /api/projects/tasks,
    PATCH/POST/DELETE mutations, repo-scoped + global modes
- **Routes**: /beta/tracker, /beta/tracker/:view, /project/:owner/:repo/beta-tracker,
  /project/:owner/:repo/beta-tracker/:view
- **Sidebar**: Tracker [Beta] in AppSidebar global nav + ProjectFolder per-repo tabs
- **Learning dashboard**: 5 Astro pages + 9 React components (InsightGrid, SessionsTable,
  BabysitterHUD, PatternDistributionChart, etc.)
- **CostsApp**: QueryClientProvider wrapper to fix SSR error

+# Rule: Durable Objects with SQLite State
+
+NEVER use `new_classes` for SQLite-backed Durable Objects.
+ALWAYS use `new_sqlite_classes` in the migrations array.
+
+**Wrong:**
+```jsonc
+"migrations": [{ "tag": "v1", "new_classes": ["MyAgent"] }]
+```
+
+**Correct:**
+```jsonc
+"migrations": [{ "tag": "v1", "new_sqlite_classes": ["MyAgent"] }]
+```
+
+**Why:** `new_classes` does not initialize the SQLite storage layer.
+Any class extending `Agent` from `@cloudflare/agents` REQUIRES `new_sqlite_classes`.
+Violation causes runtime errors: "SQLite storage not available."
