feat: Add git tag support to release workflow

- Add 'tag-version' target to create annotated git tags
- Add 'create-release' target for complete release workflow
- Enhance 'bump-version' with reminders about CHANGELOG and tagging
- Tag format: vX.Y.Z (e.g., v0.0.10)
- Prevents duplicate tags with validation
- Provides helpful reminders for manual steps

Usage:
  make tag-version          # Create tag for current version
  make create-release VERSION=0.1.0  # Full release workflow
