/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

從 /add-dir 命令入口點和現有的 add-dir 輸入 UI 開始。檢查命令參數的處理方式，以及貼上路徑的處理方式。完成的標準是：提供的目錄會直接新增，而貼上的路徑在輸入框中保持不變。
