feat: add lsof command

[a-rookie-of-C-language]

Fixes #61.

Implemented the lsof command using the Windows Native API and Win32 API.

Includes:

-p PID        Only list files opened by the specified process ID
-c COMMAND    Only list files opened by processes whose name matches COMMAND
--help        Show help
--version     Show version information
--            Stop parsing options; treat everything after this as a FILE filter

The command’s options could certainly be expanded, but this is at least a starting point.

I know I said I would prefer your native language over AI comments, and while I meant it in earnest, it still was somewhat hyperbolic. 😄 At least for PR titles and some of the description English is mandatory, so I'll use AI to translate it.
