Changed from physics-based (accumulate + damping) to vector-based:
- Horizontal velocity is SET directly, not accumulated
- Press A → cvx = -0.5 (instant, no ramp-up)
- Release → cvx = 0 (instant stop, no sliding)
- No horizontal damping = precise control
- Air strafing: same horizontal speed in air as on ground
- Can change direction mid-jump freely
- Vertical: gravity + minimal damping (0.99) for natural fall
- Jump sets cvy directly, gravity pulls back
- move_speed 0.5 (was 0.3), max_vel 2.0 (was 1.0)
- Player: move_dir tracks current direction, stop_horizontal() clears velocity
- handle_input: calls stop_horizontal when no movement key held
109 tests, 0 warnings, 0 failures
- Fix: rewrite resolve_grid_collision to push body out of solid cells
when center is inside (was only pushing to small radius from center)
- Fix: max velocity clamp (0.8) + 4x substepping prevents tunneling
- Fix: player/goblin spawn at terrain surface instead of mid-air
- Fix: gravity reduced from 0.3 to 0.08 for substepping
- Add: headless mode (--headless-ticks N) dumps grid state to file
- Add: velocity zeroing on collision for stable resting
