Three issues fixed:
1. GPX parser used browser DOMParser which doesn't exist in Node/Vite SSR.
Added async parseGpxAsync() using linkedom for server-side parsing.
2. Server-side session initialization stored waypoints in a Yjs doc
instance separate from the Vite WebSocket plugin's doc store.
Moved waypoint initialization to client-side: API returns parsed
waypoints, client adds them to Yjs after sync.
3. GPX was encoded in URL params causing HTTP 431. Now the Journal
creates a Planner session via API (POST body), and only passes
compact waypoint coordinates in URL params.
Verified: Journal route → Edit in Planner → 4 waypoints loaded,
route computed (79.3km), elevation profile, Save to Journal ready.

- Yjs WebSocket server at /sync/:sessionId for real-time collaboration
- Session creation API (POST /api/sessions) with optional GPX initialization
- Session join page with Planner layout (header, map area, sidebar)
- In-memory session store (PostgreSQL persistence deferred to infra setup)
- Custom production server entry with WebSocket upgrade handling
- Vite path aliases (~/) for clean imports
- Fix tsconfig for apps: noEmit, exclude build dir
Tasks completed: 4.1, 4.3, 4.4, 4.5
Deferred: 4.2 (PostgreSQL), 4.6-4.8 (need client-side Yjs from Group 6)
