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.

Live at http://10.244.136.121:8093/, independently re-verified by
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.

Self-contained module. Exports ISLE_RENDERER = { Renderer, VIEW_W, VIEW_H }.

  • new Renderer(canvas, { onEvent }) — pure draw: draw(ctx, state) renders whatever the physics state contains (blocks, enemies, birds, sling, HUD-ish scenery, popups). It never mutates state.
  • VIEW_W/VIEW_H (1280x720) mirror physics constants VIEW — keep them in sync; the camera lives in state (set by physics/camera), render only applies it.
  • S-3/S-5 (RC-375D84, landed): drawBlock rotates about the block COM when bl.ang is set (no-op at ang=0, so un-tipped blocks draw identically to the pre-S-3 output), and drawBird renders landed birds as live bodies alongside the spent corpses. The DOM-stub test only checks that drawing does not throw and that the sling band stops tracking a launched bird (bug #14 arm).
