Subject: [PATCH] chore: add pre-commit hook with auto-format and lint checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pre-commit hook runs prettier --write on staged frontend files, re-stages them, then checks eslint and go vet. Blocks the commit if eslint or vet fails. Stored in .githooks/ (version controlled) — enable with: git config core.hooksPath .githooks

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent)
