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: WORLD, VIEW, MATERIALS, BIRD_TYPES, ENEMY_TYPES, GRAVITY, LAUNCH_POWER, MAX_PULL, MIN_PULL, AIR_DRAG, BIRD_BOUNCE, BIRD_GROUND_FRICTION, REST_SPEED, SETTLE_TIME, BIRD_MAX_AGE, ABILITY_CD, BIRD_BONUS.

Leaf submodule: consumes nothing from P — it may be loaded first (and in the browser it is).
MATERIALS / BIRD_TYPES / ENEMY_TYPES are the balance tables: hp, dmgFactor, density, speed, bonus. The balance spec (test/balance.test.mjs) pins the per-material break budget and enemy kill budget — change a table value only with a matching spec update and a watched RED->GREEN.
WORLD.w / WORLD.ground (2400 x 900 surface) and VIEW (1280x720 design resolution) are the spatial contract; render and camera assume them.
