/add-dir should support passing a directory argument directly, and fix pasted paths being modified in the input box

Expected Behavior

I expect the ‎/add-dir command to support passing a directory path directly, for example:

/add-dir "/Users/david/Projects/caonima"

When a directory argument is provided, Command Code should add that directory directly, instead of always need to opening the interactive add-dir UI

In addition, in the existing add-dir UI, the input box should accept pasted directory paths as-is, without adding any extra characters before or after the pasted text.

Actual Behavior

Right now, ‎/add-dir does not respect a directory argument.

When I paste a directory path into the add-dir input box, the pasted text gets modified: some extra characters (e.g. something like ‎~200 or similar) are added to the beginning and the end of the path.

Additional context

No response

Start at the /add-dir command entry point and the existing add-dir input UI. Check how command arguments are handled and how pasted paths are processed. Done means a supplied directory is added directly, while pasted paths remain unchanged in the input box.
