* Trash imv deletes; add Ctrl+E to edit in Satty
Ctrl+X / Ctrl+Shift+X now move the image to the freedesktop trash via
`gio trash` instead of unconditional `rm`, so accidental presses are
recoverable from the file manager's Trash.
Adds Ctrl+E to open the current image in Satty (already in
omarchy-base.packages) and quit imv, mirroring the typical
screenshot → annotate workflow.
* Add -- separator to gio trash invocations
Prevents filenames starting with - from being parsed as options.
