docs: update changelog for v0.2.4

The main kugetsu script had its own update_queue_item_state() definition
with broken os.system() calls that overwrote the fixed version in kugetsu-index.sh.

Now kugetsu will use the fixed version from kugetsu-index.sh (which sources
kugetsu-log.sh) since that module is sourced first.

Fixes #170

+### Fixed
+- Queue daemon: Locking to prevent daemon vs manual conflicts
+- Queue daemon: Proper error handling for failed tasks
+- Queue daemon: Fix GITEA_TOKEN loading from pm-agent.env
+- cmd_delegate: Enqueue tasks instead of bypassing queue
+- 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
+
 ## [v0.2.1] - 2026-04-03
