Add trash support for macOS

[p-mng]

It seems like macOS 14 ("Sonoma", introduced in late 2023) introduced a built-in trash command (see man 8 trash). Currently, nnn only supports trash-put and gio trash. I'm aware of #1779, but neither trash-cli nor gio trash include macOS support.

I was wondering if you would be willing to add support for this command, for example using NNN_TRASH=3?

man page for reference:

TRASH(8)                           System Manager's Manual                           TRASH(8)

NAME
     trash – Moves files and directories to the user trash folder

SYNOPSIS
     trash [-h] [--help] [-s] [-stopOnError] [-v] [--verbose] FILE [FILE...]

DESCRIPTION
     The trash moves files and directories into the user trash folder.  The options are as
     follows:

     -h | --help
                display usage information for the tool and exit

     -v | --verbose
                display more verbose status

     -s | --stopOnError
                exit with an error if any move to a trash folder fails

I can't find the issue/discussion, but there was a proposal to make NNN_TRASH=3 call out to a custom plugin (e.g ~/.config/nnn/plugins/.trash) so that the user can customize that plugin to use whatever trashing method they prefer.

Feel free to raise a PR.

make NNN_TRASH=3 call out to a custom plugin (e.g ~/.config/nnn/plugins/.trash)

I don't feel familiar enough with the project (and C in general) to add this feature, but I added support for the trash command (using NNN_TRASH=3) in my fork at p-mng@cef572c. If you would be willing to add this feature and take a look at the changes I can open a PR.
