The Dockerfile only copied services/mana-sync, but go.mod has a replace
directive pointing to ../../packages/shared-go which needs to be in the
build context. Switch context to repo root and copy both packages.

Implement the foundational local-first data layer for ManaCore apps:
- New @manacore/local-store package (Dexie.js IndexedDB, sync engine, Svelte 5 reactive queries)
- New mana-sync Go service (sync protocol, WebSocket push, field-level LWW conflict resolution)
- Todo app migrated as pilot: stores read/write IndexedDB, guest mode with onboarding seed data
- PillNavigation: prominent login pill for unauthenticated users
- SyncIndicator component showing local/syncing/offline status
- GuestWelcomeModal on first visit for Todo app
- Removed demo-mode auth_required checks from Todo components (all writes are now local)
- CSP fix for local development (localhost:3001, localhost:3050)
