Subject: [PATCH] ci: add dependency caching and split into parallel jobs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Split CI into build → test + lint (parallel), add actions/cache
for node_modules keyed on bun.lock, and use --frozen-lockfile for
reproducible installs.
