fix: init script captures wrong session IDs when old sessions exist

The init script used 'tail -1' to find newly created sessions, which
fails when old sessions exist because it picks an existing session
instead of the newly created one.

The fix captures session IDs before and after creating new sessions,
then diffs to identify newly created sessions.

Fixes #172

+- Notifications: Call kugetsu_add_notification from bash instead of os.system()
+- kugetsu: Remove duplicate update_queue_item_state that overwrote fixed version
+
+### Added
+- Queue functions moved to kugetsu-index.sh for daemon access
+- kugetsu-session.sh sources required modules for daemon use
+
+## [v0.2.3] - 2026-04-06
+
+### Fixed
+- get_pending_tasks() returns proper JSON array instead of concatenated JSON objects
