fix: AABB capsule collider for rigid entities, sliding on surfaces
...
- Replace per-body collision with single AABB collider for rigid entities
- Entity has half_w/half_h defining the collider box
- Separate axis resolution: X first (min-penetration push), then Y
(velocity-direction push to handle floor/ceiling correctly)
- Sliding: when hitting a wall, only X velocity is zeroed, Y continues
- check_on_ground uses AABB bottom edge, not individual bodies
- Fix: X resolution uses minimum penetration (was velocity-based,
which pushed player through walls when velocity was zero)
- Default scene: added water pool, lava pool, wood structure, sand dune,
acid pool, stone wall obstacle
- 28/28 tests passing

feat: bigger characters (16 sub-bodies), wider terminal viewport
...
- Entity: 16 sub-bodies (was 7), radius 0.7 (was 0.4), full humanoid
shape: head, shoulders, torso, arms, hips, legs, feet
- Terminal: viewport up to 250x80 (was 120x50), uses full terminal size
- Camera: uses renderer viewport dimensions instead of hardcoded values
- Physics: constraint correction clamped to 0.5 cells max, 8 substeps
(was 4), gravity 0.04 (was 0.08), collision pass after each constraint
iteration to prevent tunneling with larger bodies
- Player: move_speed 0.3, jump_force 1.2 for bigger body
- Spawn: 6 cells above surface (was 4) for taller body

feat: AI integration - pipe protocol, test framework, replay system
...
AI Session API (src/ai/session.rs):
- GameSession wraps Game with seeded determinism
- init/init_empty, step(n), perform_action, get_state
- get_cell, get_region, get_entities, get_player, count_material
JSON Pipe Protocol (src/ai/protocol.rs):
- --mode pipe: stdin/stdout JSON line protocol
- Commands: init, step, action, get_state, get_view, get_cell,
get_region, get_entities, get_player, count_material, find_material,
record_start/stop, replay_save, run_scenario, quit
Test Framework:
- 27 Rust integration tests (tests/*.rs) covering sand, water, lava,
acid, fire physics + entity movement, damage, ragdoll
- 8 JSON scenarios (scenarios/*.json) runnable via --mode test
- Scenario assertions: cell_is, cell_is_not, no_material_in_region,
material_count_in_region, entity_alive/dead, player_on_ground, etc.
Replay System (src/ai/replay.rs):
- Record all actions + seed for deterministic playback
- ReplayPlayer::play() and play_until_tick() for debugging
- --mode replay --replay-file PATH
Other changes:
- src/lib.rs: library target for integration tests
- Collision: post-constraint collision pass to reduce tunneling
- serde + serde_json dependencies
- All enums use rename_all = snake_case for JSON compatibility
