chore: merge main (including PR #452) and resolve all conflicts

- Migration rename conflicts: keep both webhooks/ (main) and _archive/ (ours)
- Backend: accept PR #452's improved versions for learning schemas,
  sentinel clarify, agent-ai (adds getAiBaseUrl, streamTextAgent, createRunner)
- App.tsx: keep dual-scope routing architecture, add TrackerBeta routes
  to GlobalRoutes instead of inline
- RepoFolder.tsx: merge imports, remove duplicate beta-tracker nav entry
- wrangler.jsonc: combine all DOs from both sides (UxDesignAgent,
  LearningAgent, SandboxAgent) + v1_sentinel migration tag

+# 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."
