f8bd1011e9 security(memory): escape SQL ILIKE patterns to prevent injection 
- Add _escape_like_pattern() helper to escape SQL wildcards (%, _, \)
- Apply escaping in SemanticMemory.search_facts and get_by_entity
- Apply escaping in ProceduralMemory.search and find_best_for_task

Prevents attackers from injecting SQL wildcard patterns through
user-controlled search terms.

e946787a61 feat(memory): add semantic memory implementation (Issue #91) 
Implements semantic memory with fact storage, retrieval, and verification:

Core functionality:
- SemanticMemory class for fact storage/retrieval
- Fact storage as subject-predicate-object triples
- Duplicate detection with reinforcement
- Semantic search with text-based fallback
- Entity-based retrieval
- Confidence scoring and decay
- Conflict resolution

Supporting modules:
- FactExtractor: Pattern-based fact extraction from episodes
- FactVerifier: Contradiction detection and reliability scoring

Test coverage:
- 47 unit tests covering all modules
- extraction.py: 99% coverage
- verification.py: 95% coverage
- memory.py: 78% coverage

085a748929 feat(memory): #87 project setup & core architecture 
Implements Sub-Issue #87 of Issue #62 (Agent Memory System).

Core infrastructure:
- memory/types.py: Type definitions for all memory types (Working, Episodic,
  Semantic, Procedural) with enums for MemoryType, ScopeLevel, Outcome
- memory/config.py: MemorySettings with MEM_ env prefix, thread-safe singleton
- memory/exceptions.py: Comprehensive exception hierarchy for memory operations
- memory/manager.py: MemoryManager facade with placeholder methods

Directory structure:
- working/: Working memory (Redis/in-memory) - to be implemented in #89
- episodic/: Episodic memory (experiences) - to be implemented in #90
- semantic/: Semantic memory (facts) - to be implemented in #91
- procedural/: Procedural memory (skills) - to be implemented in #92
- scoping/: Scope management - to be implemented in #93
- indexing/: Vector indexing - to be implemented in #94
- consolidation/: Memory consolidation - to be implemented in #95

Tests: 71 unit tests for config, types, and exceptions
Docs: Comprehensive implementation plan at docs/architecture/memory-system-plan.md
