v0.18.0 — Locations Quick setup + place-based reminders (#4 groundwork)

#4 cleanup + Tony's house structure.

- Task.locationId (migration): reminders can attach to a place, not just a
  plant/item/animal. Add one from a location's menu (e.g. clean gutters on House >
  Exterior); the Reminders page + tasks service surface the linked location/item/
  animal.
- Locations "Quick setup": paste/confirm an indented outline → creates the nested
  tree (find-or-create by name+parent, idempotent), pre-filled with the Moon
  homestead house layout. Optional "sweep existing garden areas under Yard" moves
  every top-level place that holds plants under a new Yard parent — the
  'move all the yard stuff to a new top level' ask.
- Pure outline parser (src/lib/locations/outline.ts, +4 tests); bulk setup service
  + /api/locations/bulk. Verified end-to-end: nested tree + paths, garden sweep,
  place reminder.

Yard sub-bucketing deferred per Tony.
