Add Transcode entry to Nautilus context menu (#5635)

* Add Transcode entry to Nautilus context menu

Right-click on image or video files in Nautilus to send them to
omarchy-transcode in a presentation terminal, mirroring the existing
LocalSend integration.

* Use shlex.quote for shell-safe command construction in transcode.py

Quote both the resolved binary path and file paths via shlex.quote
instead of a custom escaper. Addresses Copilot review on #5635.
