kempersc 0d5d48568d refactor(schema): centralize slot definitions per Rule 38 
- Remove slot_uri, description, mappings from slot_usage sections
- Move these properties to centralized slot files in modules/slots/
- Keep only class-specific overrides in slot_usage (required, inlined, examples)
- Update 1,499 centralized slot files with enriched definitions
- Clean 188 class files

Violations fixed:
- slot_uri in slot_usage: 1,676 → 0
- description in slot_usage: 2,287 → 0 (moved to centralized)

Schema still validates: 816 classes, 2028 slots, 127 enums

description: "Abstract base class for all textual/derived content from videos.\n\n**DEFINITION**:\n\nVideoTextContent\
\ is the abstract parent for all text that is extracted,\ntranscribed, or derived from video content. This includes:\n\
\n| Subclass | Source | Description |\n|----------|--------|-------------|\n| VideoTranscript | Audio | Full text transcription\
\ of spoken content |\n| VideoSubtitle | Audio | Time-coded caption entries (SRT/VTT) |\n| VideoAnnotation | Visual\
\ | CV/multimodal-derived descriptions |\n\n**PROVENANCE REQUIREMENTS**:\n\nAll video-derived text MUST include comprehensive\
\ provenance:\n\n1. **Source**: Which video was processed (`source_video`)\n2. **Method**: How was content generated\
\ (`generation_method`)\n3. **Agent**: Who/what generated it (`generated_by`)\n4. **Time**: When was it generated (`generation_timestamp`)\n\
5. **Version**: Tool/model version (`model_version`)\n6. **Quality**: Overall confidence (`overall_confidence`)\n\n\
**PROV-O ALIGNMENT**:\n\nMaps to W3C PROV-O for provenance tracking:\n\n```turtle\n:transcript a hc:VideoTranscript\

- E73 is the base for all identifiable immaterial items\n- Includes texts, computer programs, songs, recipes\n- VideoTextContent\
\ are E73 instances derived from video (E73)\n\n**GENERATION METHODS**:\n\n| Method | Description | Typical Confidence\
\ |\n|--------|-------------|-------------------|\n| ASR_AUTOMATIC | Automatic speech recognition | 0.75-0.95 |\n| ASR_ENHANCED\
\ | ASR with post-processing | 0.85-0.98 |\n| MANUAL_TRANSCRIPTION | Human transcription | 0.98-1.0 |\n| MANUAL_CORRECTION\
\ | Human-corrected ASR | 0.95-1.0 |\n| CV_AUTOMATIC | Computer vision detection | 0.60-0.90 |\n| MULTIMODAL | Combined\
\ audio+visual AI | 0.70-0.95 |\n| OCR | Optical character recognition | 0.80-0.98 |\n| PLATFORM_PROVIDED | From YouTube/Vimeo\
\ API | 0.85-0.95 |\n\n**HERITAGE INSTITUTION CONTEXT**:\n\nVideo text content is critical for:\n- **Accessibility**:\
\ Deaf/HoH users need accurate captions\n- **Discovery**: Full-text search over video collections\n- **Preservation**:\
\ Text outlasts video format obsolescence\n- **Research**: Analyzing spoken content at scale\n- **Translation**: Multilingual\
\ access to heritage content\n\n**LANGUAGE SUPPORT**:\n\n- `content_language`: Primary language of text content\n- May\
\ differ from video's default_audio_language if translated\n- ISO 639-1 codes (e.g., \"nl\", \"en\", \"de\")\n"
