fix: misc fixes for observations and mental models (#209)
* fix: misc fixes for observations and mental models

* feat: improve graph retrieval for observations

- Update LinkExpansionRetriever to traverse through source_memory_ids
  for observation entity connections (avoiding data duplication)
- Remove entity link copy from world facts to observations in consolidator
- Add tests for link expansion graph retrieval
- Add directives_applied field to ReflectResult
- Include user's other changes (CLI, docs, client updates)

* fix: CI test failures

- Add mental_model_id parameter to create_mental_model function
- Fix ToolCallTrace not including reason field from ToolCall
- Improve test_link_expansion_observation_graph_retrieval to wait for consolidation with retry

* chore: reduce link expansion log verbosity

* Revert "chore: reduce link expansion log verbosity"

This reverts commit 3ce759391cead1012157785fa78fef16ef9bfe3b.

* feat: add semantic/temporal/entity links as fallback in graph retrieval

- Add fallback query for semantic, temporal, and entity links from memory_links
- Check both directions (outgoing and incoming links)
- Weight fallback results at 0.5x to prioritize entity links via unit_entities
- Fixes graph retrieval returning 0 when data has cross-cluster temporal connections

* fix: enable observations fixture for link expansion test

- Add enable_observations fixture to ensure observations are created
- Increase wait time from 10 to 30 seconds for CI reliability

"""Consolidation engine for automatic observation creation from memories.
The consolidation engine runs as a background job after retain operations complete.
It processes new memories and either:
- Creates new observations from novel facts
- Updates existing observations when new evidence supports/contradicts/refines them
Observations are stored in memory_units with fact_type='observation' and include:
- proof_count: Number of supporting memories
- source_memory_ids: Array of memory UUIDs that contribute to this observation
- history: JSONB tracking changes over time
