feat(map): high-quality movement map with spawns, cover, and wall-run surfaces

- Multi-level layout: central tower, corner platforms, stepping stones
- 6 spawn points (3 red, 3 blue) in covered alcoves with multiple exits
- Anti-spawn-camping: cover walls around spawns, 2+ exit routes each
- Wall-run surfaces on outer walls and inner tower walls (blue metal)
- Cover systems: low walls, crates, corridor walls for tactical lanes
- Ramps: cardinal ramps to central platform, corner ramps to platforms
- Visual polish: warm/cool accent lighting, sky/fog, varied materials
- Materials: concrete, dark concrete, metal, wood, crate, wall-run blue
- Decorative: barrels, hazard stripes, edge trim, accent beams
- Fixed test_fsm_runner.gd queue_free() void return parse error
- Added _ramp_mat() builder for material-based ramps

Closes #2
