* Fix datetime comparison errors by normalizing to UTC
Applied ensure_utc() to all datetime comparisons in edge_operations.py to prevent TypeError when comparing timezone-naive and timezone-aware datetimes. Removed redundant tzinfo checks since ensure_utc() handles both None and naive datetimes.
Fixed comparisons at:
- Lines 419, 423: resolve_edge_contradictions function
- Line 430: resolve_edge_contradictions function
- Line 627: resolve_extracted_edge function (removed redundant tzinfo checks)

* Add prompt name tracking to OpenTelemetry tracing spans
Add prompt_name parameter to all LLM client generate_response() methods
and set it as a span attribute in the llm.generate span. This enables
better observability by identifying which prompt template was used for
each LLM call.
Changes:
- Add prompt_name parameter to LLMClient.generate_response() base method
- Add prompt_name parameter and tracing to OpenAIBaseClient,
AnthropicClient, GeminiClient, and OpenAIGenericClient
- Update all 14 LLM call sites across maintenance operations to include
prompt_name:
- edge_operations.py: 4 calls
- node_operations.py: 6 calls (note: 7 listed but only 6 unique)
- temporal_operations.py: 2 calls
- community_operations.py: 2 calls

* Fix exception handling in add_episode to record errors in OpenTelemetry span
Moved try-except block inside the OpenTelemetry span context and added
proper error recording with span.set_status() and span.record_exception().
This ensures exceptions are captured in the distributed trace, matching
the pattern used in add_episode_bulk.

* Add group_id parameter to get_extraction_language_instruction
Enable consumers to provide group-specific language extraction
instructions by passing group_id through the call chain.
Changes:
- Add optional group_id parameter to get_extraction_language_instruction()
- Add group_id parameter to all LLMClient.generate_response() methods
- Pass group_id through to language instruction function
- Maintain backward compatibility with default None value
Users can now customize extraction per group:
```python
def custom_instruction(group_id: str | None = None) -> str:
if group_id == 'spanish-users':
return '\n\nExtract in Spanish.'
return '\n\nExtract in original language.'
client.get_extraction_language_instruction = custom_instruction

Thread group_id parameter through all extraction-related generate_response()
calls where it's naturally available (via episode.group_id or node.group_id).

group-specific language preferences.
Changes:
- edge_operations.py: Pass group_id in extract_edges()

Fixes invalid entity ID references in edge extraction that caused warnings like:
"WARNING: source or target node not filled WILL_FIND. source_node_uuid: 23 and target_node_uuid: 3"
Changes:
- Format ENTITIES list as proper JSON in prompt for better LLM parsing
- Clarify field descriptions to reference entity id from ENTITIES list
- Add explicit entity ID validation as #1 extraction rule with examples
- Improve error logging (removed PII, added entity count and valid range)
These changes follow patterns from extract_nodes.py and dedupe_nodes.py where
entity referencing works reliably.

* fix: Prevent duplicate edge facts within same episode
This fixes three related bugs that allowed verbatim duplicate edge facts:
1. Fixed LLM deduplication: Changed related_edges_context to use integer
indices instead of UUIDs, matching the EdgeDuplicate model expectations.
2. Fixed batch deduplication: Removed episode skip in dedupe_edges_bulk
that prevented comparing edges from the same episode. Added self-comparison
guard to prevent edge from comparing against itself.
3. Added fast-path deduplication: Added exact string matching before parallel
processing in resolve_extracted_edges to catch within-episode duplicates
early, preventing race conditions where concurrent edges can't see each other.

Added three tests to verify the edge deduplication fixes:

dedupe_edges_bulk now compares edges from the same episode after
removing the `if i == j: continue` check.
2. test_resolve_extracted_edge_uses_integer_indices_for_duplicates:
Validates that the LLM receives integer indices for duplicate
detection and correctly processes returned duplicate_facts.
3. test_resolve_extracted_edges_fast_path_deduplication: Confirms that
the fast-path exact string matching deduplicates identical edges
before parallel processing, preventing race conditions.
