robot 07d5290b67 perf: optimize container startup and CI pipeline ...

- Dockerfile: use Flutter tarball instead of git clone (~150MB vs 500MB+)
- Dockerfile: split into independent layers for better caching
- Dockerfile: use JRE instead of JDK, remove unnecessary packages
- devcontainer.json: remove venv/pip/claude from postCreateCommand
- ci.yml: remove redundant analyze/test in build-android job
- ci.yml: run lint and test in parallel (no dependency chain)

Estimated impact: 40min -> ~5-8min first build, ~2-3min cached
