feat(04-03): implement progressive compression engine

- Added CompressionEngine class with 4-tier age-based compression
- 7 days: Full content (no compression)
- 30 days: Key points extraction (70% retention)
- 90 days: Brief summary (40% retention)
- 365+ days: Metadata only
- Hybrid extractive-abstractive summarization with fallbacks
- Compression quality metrics and validation
- Support for missing dependencies (NLTK/transformers)
- Added transformers and nltk to requirements.txt

feat(04-02): implement context-aware and timeline search capabilities

- Completed Task 2: Context-aware and timeline search
- ContextAwareSearch class with topic classification and result prioritization
- TimelineSearch class with date-range filtering and temporal proximity
- Enhanced MemoryManager with unified search interface
- Supports semantic, keyword, context-aware, timeline, and hybrid search
- Added search result dataclasses with relevance scoring
- Integrated all search strategies into MemoryManager.search() method

All search modes operational:
- Semantic search with sentence-transformers embeddings
- Context-aware search with topic-based prioritization
- Timeline search with date filtering and recency weighting
- Hybrid search combining multiple strategies

Search results include conversation context and relevance scoring as required.

feat(04-01): create memory module structure and SQLite manager

- Created src/memory module with MemoryManager stub
- Created src/memory/storage subpackage
- Implemented SQLiteManager with connection management and thread safety
- Database schema supports conversations, messages, and metadata
- Includes proper indexing and error handling

Schema:
- conversations table: id, title, timestamps, metadata, session stats
- messages table: id, conversation_id, role, content, importance, embedding_ref
- Foreign key constraints and performance indexes
- Thread-local connections with WAL mode for concurrency
