Added unpushed tag detection to release status command to prevent
forgotten tag pushes (the critical issue from v0.10.0 release).
**Implementation**:
- Added `get_unpushed_tags()` method to GitManager
- Compares local tags with remote tags (git ls-remote)
- Handles annotated tags correctly (strips ^{} suffix)
- Added unpushed_tags to repository status dict
**CLI Enhancement**:
- `release status` now shows unpushed tags with warning emoji
- Lists all unpushed tags
- Provides helpful command to push them
**Output Example**:
```
⚠️ Unpushed Tags: 2 tag(s) not pushed to origin
- v0.9.0
- v0.10.0
💡 Push tags with: git push origin v0.9.0 v0.10.0
Or push all tags: git push --tags
```
**Testing**: Verified with current repo (no unpushed tags after push)
**Files Modified**:
- capabilities/release-management/src/release_management/git/manager.py
- capabilities/release-management/src/release_management/cli/main.py
**Documentation**: Added comprehensive IMPLEMENTATION_PLAN.md with
all 9 optimizations detailed (13.5 hours total estimated)
This solves the #1 critical issue from OPTIMIZATION_ASSESSMENT.md.
