feat: enhance task management with new file renaming feature and notification settings

- Added a new file renaming functionality in the editor, allowing users to rename files and directories in place.
- Introduced notification settings for team inbox messages and task clarifications, enabling users to receive native OS notifications for important updates.
- Updated the README to reflect the new features and provide a clearer overview of the task management capabilities.
- Improved the application icon handling for notifications across different platforms.

+## What is this
+
+A new approach to task management with AI agents.
+
+- **Assemble your team** — create agent teams with different roles that work autonomously in parallel
+- **Agents talk to each other** — they communicate, create and manage their own tasks, and leave comments
+- **Sit back and watch** — tasks change status on the kanban board while agents handle everything on their own
+- **Review changes like in Cursor** — see what code each task changed, then approve, reject, or comment
+- **Full tool visibility** — inspect exactly which tools an agent used to complete each task
+- **Stay in control** — send a direct message to any agent or drop a comment on a task whenever you want to clarify something or add new work
