fix: add JSON validation in write_index to prevent malformed index.json

The index.json was getting corrupted (ending with 'issues: }' instead of 'issues: {}').
Added validation that checks if the JSON is valid before moving the temp file.
If invalid, the write is aborted with an error message showing the problematic values.

+### 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
