`pane:get_current_working_dir()`

Returns the current working directory of the pane, if known. The current directory can be specified by an application sending OSC 7.

If OSC 7 was never sent to a pane, and the pane represents a locally spawned process, then wezterm will:

On Unix systems, determie the process group leader attached to the PTY
On Windows systems, use heuristics to infer an equivalent to the foreground process

With the process identified, wezterm will then try to determine the current working directory using operating system dependent code:

OS	Supported?
macOS	Yes, {{since('20201031-154415-9614e117', inline=True)}}
Linux	Yes, {{since('20201031-154415-9614e117', inline=True)}}
Windows	Yes, {{since('20220101-133340-7edc5b5a', inline=True)}}

If the current working directory is not known then this method returns nil. Otherwise, it returns the current working directory as a URI string.

Note that while the current working directory is usually a file path, it is possible for an application to set it to an FTP URL or some other kind of URL, which is why this method doesn't simply return a file path string.

This method now returns a Url object which provides a convenient way to decode and operate on the URL.
