address review findings on voice outlines

- remove the unused Nominatim reserve(); spacing tests now measure the
  actual transport start across processes
- start each queued building's 2 s ground-sampling budget when it
  reaches the head of the queue, and request a frame on promotion
- accept Nominatim and grounds outlines that cross the antimeridian
- let an unnamed school, university, hospital, cemetery, stadium or zoo
  area answer a grounds ask whose head noun names that kind, using only
  the part that holds the point; compare grounds names symmetrically
- charge shared OpenFreeMap consumers their own slice and keep the
  charged budget at the previous 64 MiB
- share one place-name fold, point-in-polygon, line stitching and
  nextTask helper instead of duplicates
- exclude Who's On First sources licensed only as "CC BY (equivalent)"
  or "CC0 (equivalent)"; rebuild the pack from the pinned archives
- whole-word neighbourhood alias guard; correct the outline size-limit
  comment
- restore DATA_SOURCES.md table formatting, keeping only real edits
- test behaviour instead of private engine fields
