feat: Add Zed remote SSH support (Vibe Kanban) (#1666)

* Done. Added Zed remote SSH support using the `zed://ssh/` protocol URL format.

**Generated URL format**: `zed://ssh/{user}@{host}{path}`

Examples:
- `zed://ssh/192.168.1.10/home/user/.vimrc`
- `zed://ssh/brit@scepcy/home/brit/projects/scepsy/`

* Restored the comment.

* Done. Added Zed to the frontend condition so the remote SSH host/user fields now appear when Zed is selected as the editor.

* add antigravity as an option in settings

* use early return for zed case to remove extra match statement
