Enhanced schema-list and schema-validate commands to support efficient
batch validation of multiple schemas, especially useful when the
metaschema changes.
**schema-list enhancements:**
- Added numbered references (#1, #2, etc.) to all output formats
- Simple format: [1] prefix for each schema
- Table format: # column as first column
- JSON/YAML: number field added to each schema
**schema-validate enhancements:**
- Number selection: `markitect schema-validate 1`
- Range selection: `markitect schema-validate 1-3`
- List selection: `markitect schema-validate 1,3,5`
- Batch validation: `markitect schema-validate --all`
- Filename selection: `markitect schema-validate schema.md`
- Filesystem path: `markitect schema-validate ./schema.md`
- Batch results displayed as clear summary table
- Registry schemas take precedence with filesystem fallback
- Full backward compatibility maintained
**Implementation details:**
- Added ValidationResult dataclass for structured results
- Added helper functions: parse_schema_selector, resolve_schema_source,
is_filesystem_path, format_validation_summary
- Changed schema_selector from Path to str for flexible input
- Added --all flag for validating all registered schemas
- Comprehensive error handling and helpful usage messages
**Testing:**
- All selection methods tested and working
- Backward compatibility verified
- Parsing utilities tested with unit tests
Completes Phase 5 of Schema-of-Schemas implementation.
