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

 - **Mapped installations.** OpenFreeMap military polygons use a bundled Overture/OSM name index; wide views show named points. Optional operator-configured Overpass and explicit Google Places searches keep their own source paths. Mapped data does not establish current activity or complete coverage.
 - **Place search.** Named-place fly-to uses Google Geocoding when a Maps key is configured, then Photon (`PHOTON_URL`; unset uses the public instance, empty disables it), then `/api/geocode` (Nominatim search) when neither answers. `/api/geocode` and the voice outline route `/api/geocode/outline` share one Nominatim queue (`NOMINATIM_URL`; unset uses the public instance, empty disables it): one request at a time at least 1.1 s apart, an identifying `User-Agent` and `Referer`, a short queue that refuses a burst, a pause after 429/403/5xx answers (honouring `Retry-After` in full), at most one retry after a network failure, and a per-install daily cap on public-instance requests (`NOMINATIM_DAILY_CAP`, default 50). Processes using the same installation state file atomically reserve the next public start and daily slot; restarts share that count, spacing and any pause. Public access fails closed if the state file cannot be read, locked, written or semantically validated. This coordination does not span independent installations or state directories, and the public service's total limit still applies across all installs, so heavy or shared deployments should set their own `NOMINATIM_URL`. An operator-selected endpoint is explicitly outside the public cap, spacing and durable-state requirement; an upstream cooldown is kept with the endpoint that returned it rather than leaking across operator URLs. Answers are cached on disk (outlines 90 days, places 30 days, no-results 24 hours); failures are not cached. Outlines are looked up only for an explicit ask, after bundled data and any configured Overpass, and only results whose type suits the ask are used. Administrative outline responses expose country/admin-1/admin-2 identity only when the selected Nominatim row has a recognized, unambiguous address type consistent with its own name; numeric rank, ambiguous types, missing fields and contradictory names do not manufacture identity. It is not used for systematic or bulk queries.
 - **Street and building outlines.** Voice street highlights, pointed-at buildings and grounds use the OpenFreeMap vector tiles the traffic layer already loads. Traffic and outlines share one bounded pending fetch/decode owner per immutable XYZ tile; materialized outline geometry is charged to the retained-byte ceiling and capped by coordinate count. Consumer result caches and request lifetimes remain independent, while eviction or explicit teardown cancels queued idle projections and releases their decoded owner. No Overpass request is made unless `OVERPASS_UPSTREAMS` is configured.
+- **Voice areas and place search.** Voice areas (`resolve_area`) use the same outline sources as voice outlines. Voice place search (`osm_query`, `/api/osm/features`) runs only on an operator-configured Overpass: a fixed list of kinds, a bounded box and result count, one query at a time, answers cached for a day. It never uses Nominatim.
 - **Cockpit regional briefing.** `/api/regional-brief` rounds aircraft coordinates into 0.1° cache cells, caches results for five minutes, and resolves physical regions from bundled public-domain Natural Earth polygons without reverse-geocoding requests. Google News RSS is queried with the resolved locality/region first; GDELT is used only when that RSS query fails or is empty. Google's published Google News terms restrict that source to personal, noncommercial use, so commercial deployments must disable/replace it or obtain separate permission; GDELT permits commercial dataset use with citation. The Data attribution popover identifies the active headline sources; article links retain publisher attribution. Headlines are location-query matches, not verified incidents, risk rankings, or evidence that a location is safe. Empty, partial, stale, and unavailable source states remain distinct. Open-Meteo supplies current conditions independently of the news source. `WX OFF` disables cockpit weather rendering only; the Local Info briefing still fetches its source-backed weather values and displays the required linked Open-Meteo credit.
 - **Dynamic weather presentation.** While cockpit mode is active, `/api/weather-effects` requests current Open-Meteo observations for the aircraft/camera location, rounds coordinates into 0.1° cache cells, caches results for five minutes, and may retain a stale observation for up to 30 minutes during a transient outage. WMO condition code selects the visual family; observed cloud cover, precipitation, visibility, wind speed, and wind direction bound its strength and motion. Missing or expired weather renders no synthetic atmospheric effect, and normal globe view never renders the weather overlay.
