* Optimize edge deduplication prompt for caching and clarity
- Restructure prompt to place invariant instructions at top and dynamic context at bottom for better LLM caching
- Change 'id' to 'idx' in edge context lists to avoid confusion with other identifiers
- Remove 'fact_type_id' from edge types context as LLM only needs fact_type_name
- Remove dynamic range values from prompt instructions (e.g., "range 0-N")
- Add debug logging before LLM call to track input sizes
- Add validation logging after LLM response to catch invalid idx values
- Clarify that duplicate_facts uses EXISTING FACTS idx and contradicted_facts uses INVALIDATION CANDIDATES idx

* Address terminology consistency and edge case logging
- Update Pydantic field descriptions to use 'idx' instead of 'ids' for consistency
- Fix debug logging to handle empty list edge case (avoid 'idx 0--1' display)
Note on review feedback:
- Validation is intentionally non-redundant: warnings provide visibility, list comprehensions ensure robustness
- WARNING level is appropriate for LLM output issues (not system errors)
- Existing test coverage is sufficient for this defensive logging addition
