keep tile outlines honest when the anchor tile fails to load

A building or grounds outline from tiles now needs the tile holding the
anchor: when that tile fails and only neighbours load, no neighbouring
building or area stands in. Nominatim name tags holding several
";"-separated names match each name. Document recovery from a stuck
public-Nominatim dispatch marker, correct the phone credit comment,
drive the slow-device queue test with a mocked performance clock, and
credit GitHub handles in the changelog.

 - Runtime entry: `src/main.js` calls `initAnnotations({ viewer, tileset })`, exposes `window.__gevAnnotations`, and passes the engine into the voice action runner.
 - Engine contract: `src/annotations/annotationEngine.js` owns annotation state, TTL/fade lifecycle, concurrent anchor resolution, duplicate detection keyed on geometry, cancellation on clear/newer generations, and a hard cap of 120 live marks. Deferred outline upgrades drain FIFO at concurrency 2; queued work retains the owning abort controller and is discarded on a generation change before it can fetch.
-- Resolver contract: `src/annotations/resolver.js` converts names, coordinates and screen pixels into world anchors and optional geometry. Google Geocode/Places supplies a centroid and scope; route requests use `/api/route`; ambiguous or distant results are rejected or recovered near the current view instead of drawing misleading blobs. Outline resolution keeps this order: bundled admin/place/neighborhood/Natural Earth geometry; OpenFreeMap street or pointed-building geometry where applicable; the configured OSM/Overpass admin/place/footprint/street/enclosing-area ladder; guarded Nominatim for eligible named cities, admin units, landmarks, buildings and grounds; then an OpenFreeMap building fallback that accepts a named building only when its resolved anchor lies in the selected filled footprint. Pointed-at building requests retain nearby selection within 40 m. Tile grounds answer a named grounds ask only from an area of the same name, or, when the ask's head noun names a kind of grounds (school, university/college, hospital, cemetery, stadium, zoo; "campus" alone names none), from the part of the smallest unnamed area of that class that holds the anchor (a class word elsewhere in a name, as in "University Avenue Park", does not count); a differently named area never answers. If no rung can supply honest geometry, the mark remains a point or reports the capability unavailable. A real polygon, definitive miss, configured-ladder approximation, rate limit or transient result keeps its existing finality; Nominatim is only tried after higher-priority configured sources cannot answer. Building tile selection returns the selected component and its holes; a shared vector feature ID does not establish that unrelated components are one building. Other trusted multi-part outlines and holes are retained in `anno.polygons`, with `ring` anchored to the part whose filled area contains the resolved point, outside its holes, when possible. Missing capability never invents a radius outline. Only explicitly country/state/county-scoped asks bypass near-view recovery and proximity gating; state scope requires a leading `state of …`/`the state of …` phrase, while bare names, proper names ending in “State,” and administrative geocode result types alone remain guarded. Overpass throttles remain distinct from normal transients: `Retry-After` is honored for one retry, and a repeated throttle ends only that mark's outline upgrade.

 - With no detailed-feature capability, annotations retain their pins and say
   "Detailed outline unavailable"; location focus reports the same result without
   retrying. Missing capability never synthesizes an outline from a radius.
