fix(release): improve notification step error handling and resilience

🔧 **Release Workflow Improvements**
- Add graceful error handling for discussion creation permissions
- Make discussion creation non-blocking with continue-on-error: true
- Provide helpful error messages for missing write:discussions permission
- Add conditional status reporting based on discussion creation success
- Include manual creation instructions when automatic creation fails

🎯 **Problem Resolved**
The release workflow notification step was failing with 'Resource not accessible
by integration' error when the GitHub token lacked write:discussions permission.
This fix ensures the release completes successfully even if discussion creation
fails, with clear guidance for manual creation.

✅ **Benefits**
- Release workflow no longer fails due to discussion permissions
- Better user experience with informative error messages
- Maintains community notification capability when permissions allow
- Provides fallback instructions for manual discussion creation

This resolves the v0.3.0 release notification failure and prevents future issues.
