chore: auto-fix biome on staged files via pre-commit hook

[drewstone]

What

Adds a dependency-free git pre-commit hook that auto-fixes biome (lint + format) on staged files and re-stages them, so commits land clean.

• .githooks/pre-commit runs biome check --write on staged *.{ts,tsx,js,jsx,json,jsonc} and re-stages them. No-op if biome is absent or nothing relevant is staged.
• Wired via prepare: git config core.hooksPath .githooks (git-guarded, so a consumer's git-dep install is a no-op), then the existing tsup build.
• Uses the biome already in devDeps — no husky, no lint-staged, no lockfile change.

Why

Matches agent-eval's auto-fix-on-commit behavior without adding the husky/lint-staged toolchain (which would need a lockfile bump on this repo).

Verified

Smoke: staged a badly-formatted file → hook reformatted it (const a = 2 → const a = 2) and re-staged it; the hook's own commit ran clean.
