feat: GPS waypoint logger and route planner (Issue #617)
Add phone/waypoint_logger.py — interactive Termux CLI for recording,
managing, and publishing GPS waypoints:
GPS acquisition
- termux-location with gps/network/passive provider selection
- Falls back to network provider on GPS timeout
- Optional --live-gps flag: subscribes to saltybot/phone/gps MQTT
topic (sensor_dashboard.py stream) to avoid redundant GPS calls
Waypoint operations
- Record: acquires GPS fix, prompts for name + tags, appends to route
- List: table with lat/lon/alt/accuracy/tags + inter-waypoint
distance (haversine) and bearing (8-point compass)
- Delete: by index with confirmation prompt
- Clear: entire route with confirmation
- Rename: route name
Persistence
- Routes saved as JSON to ~/saltybot_route.json (configurable)
- Auto-loads on startup; survives session restarts
MQTT publish (saltybot/phone/route, QoS 1, retained)
- Full waypoint list with metadata
- nav2_poses array: flat-earth x/y (metres from origin),
quaternion yaw facing next waypoint (last faces prev)
- Compatible with Nav2 FollowWaypoints action input
Geo maths
- haversine_m(): great-circle distance
- bearing_deg(): initial bearing with 8-point compass label
- flat_earth_xy(): ENU metres for Nav2 pose export (<1% error <100km)
Flags: --broker, --port, --file, --route, --provider, --live-gps,
--no-mqtt, --debug
