* 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.

* test: Add tests for edge deduplication fixes
Added three tests to verify the edge deduplication fixes:
1. test_dedupe_edges_bulk_deduplicates_within_episode: Verifies that
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.

* chore: Update dependencies and enhance edge resolution logic
- Add new dependencies: boto3, opensearch-py, and langchain-aws to pyproject.toml.
- Modify Graphiti class to handle additional parameters in edge resolution.
- Improve edge type handling in deduplication logic by introducing custom edge type names.
- Enhance tests for edge resolution to cover new scenarios and ensure correct behavior.
This update improves the flexibility and functionality of edge operations while ensuring compatibility with new libraries.
* refactor: Clean up test_edge_operations.py and format response returns
- Remove unnecessary stubs for opensearchpy module.
- Format return values in llm_client.generate_response for consistency.
- Enhance readability by ensuring proper indentation and structure in test cases.
This refactor improves the clarity and maintainability of the test suite for edge operations.
* bump version to 0.30.0pre5 and enhance docstring for resolve_extracted_edge function
- Update version in pyproject.toml to 0.30.0pre5.
- Add detailed docstring to resolve_extracted_edge function in edge_operations.py, clarifying parameters and return values.
This update improves documentation clarity for the edge resolution process.
* fix: Add edge type validation based on node labels
- Add DEFAULT_EDGE_NAME constant for 'RELATES_TO'
- Implement pre-resolution validation to reset invalid edge names
- Add post-resolution validation for LLM-returned fact types
- Rename parameter from edge_types to edge_type_candidates for clarity
- Add comprehensive tests for validation scenarios
This ensures edges conform to edge_type_map constraints and prevents
misclassification when edge types don't match node label pairs.
