[0x0a0d]

• add env PROXYCHAINS_CONFIG_FD= to proxychains4 that will be used to get content and parse before using file parsing (default behavior)
• add proxychains-cli that take and parse inline config to fd(3) then pipe to proxychains4
• add cli test in /tests/cli/test-cli.sh
• add uninstall to Makefile
• add _proxychains-cli to complications/zsh
• more details read more on README-CLI.md

ok, as usual all your AI generated content again makes this a huge PR, which takes every reload take half a minute. for now, exclude all your README and zsh etc additions until we got the proxychains4-cli, Makefile, and libproxychains.c right so i dont have to waste my time with secondary stuff until the primary stuff is right.
