Fixes #769

Summary

Added the ConnectionPool class to src/infrastructure/db_pool.py with comprehensive unit tests in tests/infrastructure/test_db_pool.py.

Changes

New Files

src/infrastructure/db_pool.py - Thread-local SQLite connection pool
tests/infrastructure/test_db_pool.py - Unit tests

Modified Files

.gitignore - Removed src/infrastructure/db_pool.py from ignored files

Features

The ConnectionPool class provides:

get_connection() - Returns a valid sqlite3 connection (creates DB if needed)
close_connection() - Cleans up thread-local storage
connection() context manager - Yields and closes properly
Thread-local storage - Multiple calls from same thread reuse the same connection
Thread safety - Different threads get different connections

Tests

24 test cases covering:

Initialization (string/Path paths, thread-local setup)
Connection retrieval (valid connections, DB file creation, row_factory)
Connection reuse within same thread
Thread isolation (different threads get different connections)
Cleanup (close_connection, close_all)
Context manager (yields, closes on exit, closes on exception)
Concurrent access and thread safety
Integration (basic CRUD, multiple pools)

All tests pass with tox -e unit.
