ci: split PR check and deploy workflows

build.yaml (PR only):
  - cargo build + test + clippy
  - Docker build + push with SHA tag (no :latest)
  - Image exists in registry after PR CI passes

deploy.yaml (main push only):
  - docker pull SHA image (already in registry from PR)
  - docker tag as :latest
  - docker push :latest
  - No rebuild, no cargo steps
