Add mobile app, map-core, nearby sync, and activity recording specs
mobile-app: Unified React Native + Expo app combining Planner and
Journal. OAuth2 PKCE auth, MapLibre maps, versioned REST API with
Zod schemas, configurable server URL, offline SQLite, Web Push relay
notifications. TanStack Query + Zustand state management. Jest +
Maestro testing. 76 tasks across 5 phases.

map-core-package: Extract renderer-agnostic map definitions (tiles,
color palettes, POI categories, z-index) into @trails-cool/map-core.
Pure refactor preparing for MapLibre on mobile. 27 tasks.

mobile-activity-recording: GPS recording, live stats, HealthKit/Health
Connect export. Separated from mobile-app for independent scheduling.

mobile-nearby-sync: BLE route sync between nearby devices for offline
group riding. QR waypoint sharing as simpler v1. TXQR noted as future.

journal-rest-api spec: Full API contract — endpoints, auth, pagination,
errors, discovery, versioning, BRouter proxy.

## ADDED Requirements
### Requirement: Download routes for offline
The system SHALL allow users to download route data (GPX, waypoints, metadata) for offline access.
#### Scenario: Download a route
- **WHEN** the user taps "Download for offline" on a route
- **THEN** the route GPX, parsed waypoints, and metadata are stored in the local SQLite database
#### Scenario: View offline route
- **WHEN** the user views a downloaded route without network connectivity
- **THEN** the route is loaded from the local database and displayed on the map with cached tiles
#### Scenario: Delete offline data
- **WHEN** the user removes a route from offline storage
- **THEN** all cached data for that route (GPX, tiles, metadata) is deleted from the device
### Requirement: Map tile caching
The system SHALL cache map tiles for downloaded route regions so maps are viewable offline.
#### Scenario: Tile download for route region
- **WHEN** a route is downloaded for offline use
- **THEN** map tiles covering the route bounding box at relevant zoom levels are cached locally
#### Scenario: Storage budget
- **WHEN** the total offline storage exceeds the configured budget (shown on Profile tab)
- **THEN** the system warns the user and suggests removing older offline routes
### Requirement: Offline edit queue
The system SHALL queue route edits made offline and sync them when connectivity returns.
#### Scenario: Queue edits while offline
- **WHEN** the user edits a route without network connectivity
- **THEN** the changes are saved to a local edit queue and a sync-pending indicator is shown
#### Scenario: Sync on reconnect
- **WHEN** the device regains network connectivity
- **THEN** queued edits are sent to the Journal API in order and the sync indicator clears
#### Scenario: Conflict on sync
- **WHEN** the server version of a route changed while the user was offline
- **THEN** the system warns the user and applies last-write-wins, preserving the local version
