* feat(geohash): add in-app Geohash Picker map with quadrant drill-down and Activity integration
- New GeohashPickerActivity hosting a WebView with Leaflet-based picker
- Adds map icon next to custom geohash input in LocationChannelsSheet
- Picker allows quadrant selection and subquadrant drill-down; returns selected geohash
- Register activity in AndroidManifest
perf(picker): improve map performance and correctness
- Use LayerGroup and clearLayers() on redraw to avoid stale overlays
- Use Leaflet canvas renderer for rectangles to reduce DOM and improve perf
- Make labels non-interactive and pointer-events: none to avoid gesture overhead
- Fix initial mega-label artifact by grouping and clearing labels with cells
chore: add asset geohash_picker.html with minimal geohash helpers (bounds/encode/adjacent)
* remove accidentally committed submodule.
* fix some issues
* better geohash labels on map
* design wip
* countries green
* wip
* geohashpicker: pan + zoom; start from current geohash channel

* fix: send action messages to correct chat
* fix(action): avoid double local echo for action messages in geohash channels
When sending /hug or /slap in a location (geohash) channel, CommandProcessor
was adding a local echo and then routing to NostrGeohashService, which also
adds a local echo. This resulted in duplicate action messages on the sender’s
screen.
Change: detect when the selectedLocationChannel is a Location and, in that
case, skip adding the local echo in CommandProcessor and only call the
onSendMessage transport callback (NostrGeohashService will add the echo with
proper metadata). Private and mesh (non-location) behavior is unchanged.
