- Introduced a new function `load_graph_schema_full` to parse and cache both typical and prohibited edge types from the graph schema.
- Updated `load_graph_schema` to utilize the full schema for improved edge type extraction.
- Added `get_topology_info` to retrieve typical and prohibited edges for source/target pairs.
- Implemented `validate_intra_note_edge` and `validate_edge_against_schema` for schema validation of intra-note edges.
- Enhanced logging for schema validation outcomes and edge handling.
- Updated documentation to reflect new validation features and testing procedures.
- Updated provenance priorities and introduced a mapping from internal provenance values to EdgeDTO-compliant literals.
- Added a new function `normalize_provenance` to standardize internal provenance strings.
- Enhanced the `_edge` function to include an `is_internal` flag and provenance normalization.
- Modified the `EdgeDTO` model to include a new `source_hint` field for detailed provenance information and an `is_internal` flag for intra-note edges.
- Reduced the provenance options in `EdgeDTO` to valid literals, improving data integrity.
