Relay dc68c6e3dd Physics upgrade + repo modularization (RC-375D84)
Delivered by Hermies Qwen, gated and deployed by Relay.

- Board tip/topple: full continuous rotation when a board's center of
  mass passes its support edge (Q1: smooth pivot swing, no discrete
  snap). Falling boards deal impact damage and can kill enemies in
  their fall path.
- Falling-object impact damage: blocks and birds can now kill enemies
  from vertical drops and side plows (velocity-aware crush gate),
  chain momentum transfers correctly through stacks (mass-weighted
  contact), repeated impacts finish tougher enemies.
- Landed-bird physics: a bird resting on a board remains a real
  physical body under continuous gravity (Q2: no lifetime timer). If
  its platform is destroyed it falls, damages what it lands on
  (chain reaction), and can kill enemies.
- Repo modularized: folders = modules, subfolders = submodules,
  architecture.md + MODULES.md at root, an agents.md card in every
  module and submodule (17 total).
- Test suite grown from 27 to 47 (20 new RED-watched tests for the
  above behaviors), all green. Golden differential against the
  original core confirmed the only behavioral changes are the
  intended ones.

Relay (full suite re-run, module structure check, headless Chromium
smoke) before this push.

RC-375D84 S-2. Module map: MODULES.md; runtime model: architecture.md.

Installs into P: aimVector, trajectory.

  • aimVector(g, sling, drag) clamps drag to [MIN_PULL, MAX_PULL] and maps it to a launch velocity. The pull clamp is what makes full-power shots deterministic (the balance spec relies on it).
  • trajectory(g, x, y, vx, vy, steps) is the preview integrator; it must track the real flight — there is a dedicated test arm ("trajectory preview tracks the real flight"). If you change integration in stepPhysics, change it here in lockstep.
  • Consumes: LAUNCH_POWER, GRAVITY, AIR_DRAG, BIRD_BOUNCE, WORLD, BIRD_GROUND_FRICTION.
