Phase 0+1 of the browser viz effort:
- core: drop unused `rand` dep (removes getrandom/libc → clean wasm32 build);
derive serde on DungeonConfig + 5 sub-configs so the bridge can (de)serialize
- reikhelm-wasm: thin wasm-bindgen cdylib exposing generate(seed, config_json)
-> JSON envelope (tiles as int codes, regions, edges, per-pass snapshots) and
default_config_json(); holds no generation logic
- workspace: add reikhelm-wasm member; default-members keeps host cargo
test/clippy on core+viz only
- reikhelm-web: vanilla-JS + Canvas 2D renderer running the real core live in
the browser. Atmospheric look — lit stone floor, raised stone walls with
rim-lit carved edges + top bevel, room light-pooling, amber door thresholds,
vignette. Controls: seed/reroll, 9 config sliders, stage scrubber, semantic
overlays (region outlines / graph / grid). window.reikhelm hooks for
Playwright-driven iteration.
Core stays 115 tests green. Driven + screenshotted via Playwright MCP.

Default was a pure MST (extra_edge_ratio 0.0), which reads as a linear
chain of rooms. Retune DungeonConfig::default to min_leaf 8 / max_depth 5,
rooms 5..=11, and extra_edge_ratio 0.30 — ~17 interconnected rooms with
loops. Validation inequality still holds (8 - 2 >= 5); boundary test now
uses an explicit edge-case config since the default no longer sits on it.

Corridors carve center-to-center and pierce room walls, so the old
wall-threshold rule placed almost no doors. Detect the pierced-wall
threshold (corridor floor outside a room, room on one side, corridor on
the opposite) and mark it Door with probability door_chance (default
0.5), else leave it an open archway. Connectivity is via corridor floor,
independent of doors.

Lets downstream determinism tests compare maps with `assert_eq!` instead
of a serde-string workaround. Auto-gated on T (Grid<f32> gets only
PartialEq); Map has no float fields so Eq is sound.
