implemented workaround for nvim copy via OSC52

[ishay320]

When using Neovim in a remote session, OSC52 clipboard sequences are being printed to the local terminal instead of being routed to the remote terminal. This breaks clipboard synchronization for remote users. neovim/neovim#28792

that is a workaround to the problem in #146 that on the remote-nvim side that is connected to ssh it will parse the osc52 and pass it to clipborad.

In config need to add something like:

if os.getenv("SSH_CLIENT") ~= nil then
	local function noop()
		return {}
	end
	vim.g.clipboard = {
		name = "OSC 52",
		copy = {
			["+"] = require("vim.ui.clipboard.osc52").copy("+"),
			["*"] = require("vim.ui.clipboard.osc52").copy("*"),
		},
		-- NOTE: OSC 52 paste is a security risk, so most terminals disable it
		paste = {
			["+"] = noop,
			["*"] = noop,
		},
	}
end

Hey there, I've tested your fork and OSC 52 copying still does not work over SSH on my setup.
Would you mind sharing the relevant parts of your config and test setup ?
Are you testing this over SSH ? What's your terminal emulator ?

I'm using ghostty for the terminal that opens the connection, and I checking over ssh.
To check if the OSC52 works for you, ssh normally to the server, open nvim with the config above and try to copy to the + register, if it works then it should work.
Also when you use the plugin to remote, keep the status of the connection open because it stdout all the stuff from the remote, and you would see the print of the copy there.
