fix: scope all git, activity, webhook, and summarize-title routes to correct project store

- Fix 30 git routes to use getScopedStore(req) instead of global store
- Fix activity GET/DELETE routes to use scoped store
- Fix POST /api/github/webhooks to use scoped store for badge updates
- Fix POST /api/ai/summarize-title to use scoped store for settings
- Fix GET /api/git/worktrees to use scoped store for task listing
- Add projectId parameter to all git and activity frontend API functions
- Update useActivityLog hook to pass projectId through

+ * Provides canonical counting logic for projects routed to a node.

+ * **Runtime Behavior:**
+ * - Projects with `nodeId` pointing to a remote node → run on that remote node
+ * - Projects with `nodeId` pointing to a local node → run on that local node
+ * - Projects without `nodeId` (unassigned) → run on local in-process runtime
+ *
+ * **Counting Rules:**
+ * - Local nodes: include both explicitly-assigned projects AND unassigned projects
+ * - Remote nodes: include only explicitly-assigned projects
