fix: Resolve Python IndentationError in version bump workflow

 **Version Bump Workflow Fixes:**
- Fix Python IndentationError in inline script that was causing exit code 1
- Replace complex inline Python regex with dedicated scripts/get_version.py script
- Simplify NEW_VERSION extraction logic for better reliability
- Add comprehensive testing script to verify workflow logic locally

 **Specific Changes:**
- Create scripts/get_version.py for clean version extraction
- Update .github/workflows/version-bump.yml to use new script approach
- Remove problematic multi-line Python string with indentation issues
- Add error handling and validation in version extraction

 **Testing Enhancements:**
- Create test_version_bump_workflow.py for local workflow testing
- Add test_version_extraction.py for debugging version regex issues
- Verify all workflow steps work correctly before GitHub Actions execution
- Test version bump, extraction, commit, and tag creation logic

 **Verification:**
- All workflow tests pass locally
- YAML syntax is valid
- Version extraction works correctly (0.3.0  0.3.1)
- No more IndentationError or AttributeError issues
- Ready for GitHub Actions execution

**Expected Results:**
- Version Bump workflow should complete successfully
- Create commit 'Bump version to 0.3.1'
- Create and push git tag 'v0.3.1'
- Automatically trigger Release workflow for PyPI publication
