The reference six-lever controller: Platformer component (jump feel as data), decomposed input/move/gravity/jump/anim engine sub-systems (each disable-able), JumpRequested/Landed/StateChanged events, gravity policy enum, and the opt-in scaffolding (moving/crumble platforms w/ rider carry, pickups+score, springs, hazards+Life, checkpoints/goal). Reuses the shared esys_move collision. Also fixes a latent SSA-name collision in ludic_sweep_entity that triggered once a program declared >=11 events. Reseeded; C-free fixpoint holds. 3 new regression cases (100 passed, 0 failed). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Builtin Platformer controller (#58) — the reference implementation of the six-lever extensibility contract, shipped as the source package ludic.platformer. Movement feel is all defaulted POD data (Platformer { move_speed, jump_height, apex_frames, fall_gravity_mul, coyote_frames, jump_buffer_frames, air_jumps, policy, … }); the controller is decomposed into small engine-owned sub-systems — input (Input phase), move/gravity/jump (FixedUpdate, before the shared esys_move sweep) and animation-state (LateUpdate, after it) — each independently switch-off-able with disable system <fn>. It owns movement policy only and reuses the engine Body/Collider swept-AABB collision. Jump feel derives gravity + impulse from height/apex, with coyote time, jump buffering, variable jump height and multi-jump; every jump decision emits a cancellable JumpRequested / JumpPerformed / Landed / StateChanged event, and a gravity policy enum (asymmetric / symmetric / floaty) is the formula hook. Ships the opt-in game-loop layer too (scaffolding.ludic): moving & crumbling platform blocks with rider carry, collectibles + Score, springs, hazards + a light Life/i-frames model, and checkpoint/goal triggers. Deterministic integer Q16.16 throughout. Examples: examples/games/platformer_demo.ludic, examples/games/platformer_scaffolding.ludic. Also fixes a latent codegen bug in ludic_sweep_entity (an SSA register name collided once a program declared ≥11 events).
