New `map` tool (menu + `meshtools map` CLI) that plots the mesh's
location-sharing nodes over a real OSM street basemap rendered as Unicode
braille — streets, rivers, water, and place names — the mapscii idea, but
able to plot our own nodes and live inside the TUI.
- core/mvt.py: dependency-free MVT/protobuf vector-tile decoder.
- core/geo.py: Web Mercator + a pannable/zoomable Viewport and tile math.
- services/basemap.py: OpenFreeMap vector tiles (free, no API key), resolved
from the versioned TileJSON, disk-cached, offline-safe (stdlib urllib only).
- ui/mapcanvas.py: colored braille canvas (per-cell priority, line raster,
polygon fill, collision-avoided labels), emits truecolor ANSI.
- ui/map_render.py: compositor — basemap styling + node markers with names.
- ui/map_screen.py: full-screen screen; wasd/arrows pan, =/- zoom, r reset,
Esc/q exit; background tile loading. Offline falls back to nodes on a grid.
- tools/map.py: interactive in the menu, one-shot static render on the CLI.
Repeaters are prioritised over leaf nodes via advert type: threaded `node_type`
through Observation/HeardNode and the persistence layer (schema v4->v5, with an
idempotent migration adding observations.node_type). Added
TuiSession.base_body_size() so a full-screen screen can size itself to the frame.
Tests: tests/test_map.py (24) cover MVT decode against a real cached tile
fixture, projection, the canvas, the compositor, offline behavior, and the
interactive pan/zoom/reset logic. Full suite: 261 passing.
