[dependabot]

Updates the requirements on aiosqlite to permit the latest version.

Changelog

Sourced from aiosqlite's changelog.

v0.22.1

Bug fix release

NOTE: Starting with v0.22.0, the aiosqlite.Connection object no longer inherits from threading.Thread. If not using aiosqlite as a context manager, clients must await connection.close() or call connection.stop() to ensure the helper thread is completed and terminated correctly. A ResourceWarning will be emitted for any connection that is garbage collected without being closed or stopped.

• Added synchronous stop() method to aiosqlite.Connection to enable safe cleanup and termination of the background thread without dependence on having an active event loop (#370)

Review by Kai

The connection usage is clear: aiosqlite.connect() is called directly (not as a context manager), and await _db.close() is called explicitly on shutdown. This pattern is fully compatible with v0.22.x.

PR Review: Clean

pyproject.toml, line 13 - the single-line change bumps aiosqlite>=0.19.0 to >=0.22.1.

The critical breaking change in v0.22.0 is that aiosqlite.Connection no longer inherits from threading.Thread, requiring explicit await connection.close() (or connection.stop()) when not using a context manager. Checking src/kai/sessions.py:

• Line 76: connection opened via aiosqlite.connect() (not a context manager - the pattern that requires explicit close)
• Lines 194 and 1132: both shutdown paths call await _db.close() explicitly

The codebase already handles cleanup correctly. No issues found. Safe to merge.
