## Summary

Deliver `@suaveplan/r3f-character` on the genesis branch from scratch at enterprise quality. The package provides a full character controller for 3D games in React Three Fiber. It wires `@suaveplan/character-physics` (capsule controller) to a Rapier rigid body via the `@suaveplan/r3f-physics-rapier` backend; drives Three.js `AnimationMixer` for locomotion blend tree (idle/walk/run/jump/fall); applies `@suaveplan/animation-events` foot IK and procedural modifiers; and exposes a `Character` component and `useCharacter()` hook. Genesis adds structured errors, OTel frame-time histogram, and 100% coverage.

## Available workspace deps

`@suaveplan/error`, `@suaveplan/types`, `@suaveplan/character-physics`, `@suaveplan/animation-events`, `@suaveplan/ik-solver`, `@suaveplan/events`, `@suaveplan/r3f-physics-rapier`, react, `@react-three/fiber`, `@react-three/drei`, three.
