Update tag protection policy structure per feedback

- Changed from simple protected_tags list to comprehensive tags structure
- Added enforcement, scope (include/exclude), operations, naming, and bypass configuration
- Updated TypeScript types to match new structure
- Rewrote TagProtectionChecks evaluator to validate all aspects of tag protection
- Checks enforcement level, scope patterns, operation restrictions, naming constraints, and bypass actors
