Subject: feat(map): layer manager — satellite/charts/hybrid + wind toggle,
 long-press picker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

MapLayerManager: all raster sources registered at style-build time,
visibility toggled on demand. Persists base preset and wind state to
SharedPreferences. Sources: Google satellite, NOAA RNC charts
(tileservice.charts.noaa.gov), OWM wind, OpenSeaMap seamarks.

LayerPickerSheet: bottom sheet with chip group (Satellite/Charts/Hybrid)
and wind toggle, launched from map long-press.
