Add deliverables-to-todos sync feature

Dashboard now automatically syncs milestone deliverables to todos:
- On load, checks each milestone's deliverables table
- If a deliverable doesn't exist as a todo (matched by text + milestone), adds it
- Maps deliverable status to todo priority (Done=completed, In Progress=high, Not Started=medium)
- Saves updated todos.md if any items were added

Also updated CLAUDE.md to document the sync behavior.

+### Dashboard Data Sync
+
+The dashboard automatically syncs data between documentation files:
+
+- **Deliverables → TODOs**: When loading a project dashboard, deliverables from `milestones.md` tables are synced to `todos.md`. If a deliverable doesn't exist as a todo (matched by text + milestone ID), it's added with the appropriate `@M#` tag and priority.
+- **TODOs → Milestone Progress**: The milestone progress bar is calculated from linked todos (items tagged with `@M#`), not from the deliverables table.
+
+This means you can define major work items in milestone deliverable tables, and they'll automatically appear in your todo list for tracking.
+
