Geo Alert (Tools › Geo Alert): a single geofence around a snapshotted
waypoint. Beeps + alerts on crossing into (arrive) / out of (leave) the
radius per mode, with edge hysteresis and silent first-eval seeding. Adds
a proximity Beeper that ticks faster the closer to the target while inside
the radius — independent of the discrete arrive/leave alert.
Trail auto-pause (Trail › Settings): freezes the trail timer + sampling
after the device sits still for a configurable delay, resuming on the next
real movement. New paused state in TrailStore (distinct from Stop); Summary
shows "paused".
Persisted via new NodePrefs fields; schema bumped 0xC0DE0012 → 0xC0DE0014
with clamps so upgraders start with both features off.
