Add user-configurable timezone and 12/24-hour preferences, then wire them through settings, runtime snapshots, scheduler payloads, wait handling, notifications, backups, memory, plugin metadata, and frontend formatters.
Keep UTC as the boundary for absolute instants while serializing user-facing dates in the configured or browser-resolved timezone. Preserve scheduler wall-clock inputs in the selected timezone, propagate TZ into desktop/runtime process environments, and restart active desktop sessions when the runtime timezone changes.
Cover the risky paths with timezone regression tests for settings normalization, auto and fixed timezone resolution, scheduler round-trips, memory timestamp conversion, and desktop timezone sync.

Add @extension.extensible decorators to all plugin API handler methods and core plugin functions to enable extension points. Implement plugin hooks system allowing plugins to define custom behavior via hooks.py file. Add call_plugin_hook function to execute plugin-specific hooks for events like uninstall, save_plugin_config, and get_plugin_config. Introduce uninstall_plugin function that calls uninstall hook before deletion. Move circular
