feat(voice): add reusable geometry actions

- turn named places and mapped landmarks into reusable bounded areas
- count loaded records inside resolved, drawn and annotated geometry
- find recent imagery for an area, the view or the pointer snapshot
- keep osm place search behind an operator-configured overpass endpoint
- preserve cancellation, ownership and follow-up memory across every action
- cover geometry, provider lifecycle, cache isolation and voice routing

+## Unreleased — voice geometry

+- `resolve_area` turns a named place into a reusable area and can outline
+  it. It uses the same outline sources as voice outlines: bundled Natural
+  Earth regions, countries, states and counties, US Census places and
+  neighborhoods, then the guarded Nominatim outline, then Overpass only when
+  `OVERPASS_UPSTREAMS` is set. Every part and hole is kept. A name several
+  countries or states share ("Georgia", "Punjab") is asked about unless the
+  view is inside one of them. Administrative geometry is stored only when its
+  source identity agrees with the requested unit; stale or unverified units
+  are refused instead of relabelled. Clarification IDs have a documented
+  bounded grammar and round-trip through the production tool schema.
+- "Draw an area around <landmark>" outlines the mapped area enclosing it,
+  or a 250 m buffer marked approximate.
+- `analyst_query` counts inside an area (`area`), the area you drew
+  (`drawn`) or an outline on the map (`annotation`); region counts include
+  every part and leave out holes.
+- `find_imagery` shows the best recent acquisition for an area, the view or
+  the spot under the pointer through the Recent Imagery panel, and stops if
+  you change the panel or turn the layer off while it searches.
+- `osm_query` ("hospitals in Kathmandu") lists places of one kind into a
+  session-only OSM Places layer. It is offered only when
+  `OVERPASS_UPSTREAMS` is set; public Nominatim is never used for it.
+  Turning OSM Places off while a search is pending cancels that action without
+  re-enabling the layer or committing stale results or follow-up memory.
