feat: Add tag temporal sorting for automatic chronological tag ordering

Implements automatic tag temporal sorting to eliminate manual ordering requirements
for API Compatible Tags in recursive dependency resolution.

Features:
- New -EnableTagSorting parameter (disabled by default)
- Automatic tag date fetching using git for-each-ref
- Chronological tag sorting based on actual git tag creation dates
- Priority-based tag selection algorithm favoring specified "Tag" values
- Relaxed temporal ordering requirements when enabled
- Comprehensive debug and verbose logging

Benefits:
- Eliminates manual temporal ordering burden for users
- Reduces configuration errors and maintenance overhead
- Enables flexible API Compatible Tags ordering
- Provides accurate chronological selection using real git dates
- Maintains full backward compatibility

Technical Implementation:
- Get-GitTagDates function for efficient tag date retrieval
- Sort-TagsByDate function with PSCustomObject for reliable sorting
- Enhanced Update-RepositoryDictionary with intelligent tag selection
- Improved Get-TagUnion with temporal sorting support
- Tag date caching in repository dictionary for performance

Breaking Changes: None (opt-in feature, disabled by default)

+## [4.2.0] - 2025-01-16
+
+### Added
+- **Tag Temporal Sorting**: New `-EnableTagSorting` parameter enables automatic chronological tag ordering using actual git tag dates
+- Intelligent tag selection algorithm that prioritizes existing/new "Tag" values when resolving repository conflicts
+- `Get-GitTagDates` function for efficient tag date fetching using `git for-each-ref`
+- `Sort-TagsByDate` function for chronological tag sorting with comprehensive debug logging
+- Enhanced `Get-TagUnion` function with temporal sorting support when tag dates are available
+- Priority-based tag selection: prefers specified "Tag" values over other compatible tags when both are compatible
+- Fallback to chronologically most recent tag when neither existing nor new "Tag" is compatible
+- Comprehensive verbose and debug logging for tag temporal sorting operations
+- Tag date verification and temporal order display in verbose mode
+- Relaxed temporal ordering requirements when `-EnableTagSorting` is enabled
+- Tag date caching in repository dictionary for performance optimization
+
+### Changed
+- Enhanced repository dictionary structure to include `TagDates` field for storing tag date mappings
+- Improved tag selection logic in all API compatibility scenarios (Strict-Strict, Strict-Permissive, Permissive-Permissive, Permissive-Strict)
+- Updated summary report to display tag temporal sorting status and statistics
+- Enhanced union algorithm to use temporal sorting when enabled, falling back to original logic when disabled
+- Improved error handling for tag date parsing and git command failures
+
+### Fixed
+- PowerShell string interpolation issues with datetime formatting in log messages
+- Improved tag sorting object creation using `[PSCustomObject]` for reliable `Sort-Object` operations
+- Enhanced temporal verification logging with proper variable delimiting
+
+### Performance
+- Minimal server impact: tag dates fetched only once per repository after initial checkout
+- Efficient `git for-each-ref` command usage instead of individual `git log` calls per tag
+- Tag date caching eliminates redundant git operations during recursive processing
+
+### Backward Compatibility
+- **Non-breaking**: All existing configurations work without modification
+- **Default behavior**: `-EnableTagSorting` is disabled by default, maintaining v4.1.x behavior
+- **Opt-in feature**: New functionality only active when explicitly enabled
+- Manual temporal ordering requirements preserved when tag sorting is disabled
+
