chore(release): v0.6.0

Self-hosted Protomaps vector basemap, replacing the hosted CARTO raster tiles.
A single Netherlands .pmtiles file is served same-origin at /basemap/nl.pmtiles
(HTTP range, gzip-bypassed) and rendered with protomaps-leaflet; the deploy
provisions the pmtiles CLI and builds the extract on the server. Attribution is
now OpenStreetMap + Protomaps (no CARTO; no user IP leaves to a tile host).
