Subject: [PATCH] fix: docker build out-of-disk issue - aggressive cleanup

- .dockerignore: exclude build/cache/docs to reduce build context (59 lines)
- Dockerfile: add aggressive cleanup (cache, registry, git) after cargo build
- Dockerfile: use --locked flag for reproducible builds
- build.yaml: add pre-build disk cleanup (docker + cargo cache)
- build.yaml: clean cargo before Docker build to free space
- build.yaml: show disk usage before/after for debugging

Fixes 'No space left on device' error during Docker build in runner
