refactor(ci): replace release workflows with release-pilot (#254)

* refactor(ci): replace release workflows with release-pilot

Integrate release-pilot GitHub Action to simplify release management:

- Add release-pilot configuration with multi-crate support
- Replace dev_release.yml, weekly_release.yml, and deploy.yml with single workflow
- Auto-update version references in README on release
- Reduce release workflow code from ~580 to ~130 lines (78% reduction)

Release behavior unchanged:
- Dev releases on push to main
- Stable releases on Wednesday 9AM UTC schedule
- PR labels (release:major/minor/patch) determine version bump
- Crates published in dependency order with 30s delay

* chore(auto-fix): format code and fix clippy warnings
