Git hooks

pre-commit — runs on every commit:

• bun run lint — Biome linter check
• bun run typecheck — TypeScript type check

pre-push — runs on every push:

• bun run lint — Biome linter check
• bun run typecheck — TypeScript type check
• bun run test — Vitest test suite with coverage

These hooks bring CI feedback to your local workflow. CI still runs the full suite (including build, package export validation, and TypeDoc generation) on every pull request and push to main.
