Add comprehensive test suite for BuddAI v3.1

- Implemented tests for database initialization, SQL injection prevention, auto-learning pattern extraction, module detection, complexity detection, LRU cache performance, session export, actionable suggestions, repository indexing, search query safety, and context window management.
- Utilized SQLite for database operations and temporary directories for test isolation.
- Included detailed output for test results with color-coded pass/fail indicators.
