feat(sasquatch): answer 'closest spot to me' locally + stop crew hijack

1) Proximity intent: 'closest / near me / nearby' + spots is handled ON DEVICE —
   the fix is read locally (fresh, else cached) purely to sort distances, and
   nothing is transmitted (not to relays, not to the AI). Answers the nearest 3
   with distances and says location never left the device.
2) System-prompt guardrail: the AI CANNOT see the user's location — for
   closest/near-me it now says so and points at the map's Near Me (or asks for a
   city), instead of guessing.
3) Intent hijack fix: a question mentioning both a crew and a spot was routed to
   find_crews ('crews' was checked before 'spots'). Spots now win when both
   appear.
