chore: remove lefthook git hooks

Drop lefthook: it duplicated the CI gates (typecheck/lint/format:check/knip/
build/test) and wasn't even auto-installed (no prepare script), so it only
ever ran on one machine — not a real gate. CI is the authoritative gate for
everyone; formatting during development is handled by the Claude Code
PostToolUse hook (.claude/hooks/format-on-edit.mjs), which is unaffected.

 - **Scope**: internal packages are `@figwright/*`; only `@figwright/mcp` is published to npm.

 Claude Code specifics:
 
 - This repo **is** a Figma MCP server. The project-scoped `.mcp.json` launches the local build (`packages/mcp/dist/index.mjs`), so after changing `packages/mcp` or `packages/shared` you must `pnpm build` and restart the MCP connection before the `figwright` tools reflect your change.
-- A pre-commit hook formats and lints staged files automatically — don't hand-format.
+- There are no git hooks; CI is the gate. When you edit through Claude Code, the PostToolUse hook (`.claude/hooks/format-on-edit.mjs`) auto-formats and lints the file — don't hand-format.
 - The canonical checks before pushing are `pnpm typecheck && pnpm lint && pnpm format:check && pnpm knip && pnpm build && pnpm test` (the same gates CI runs).
