Skill: get-nvim-files
Author: lxgreen
Description: Lists all files currently open in any running nvim instance by querying nvim's RPC sockets. Use when the user asks what's open in nvim, what file nvim has, or wants to know their nvim buffer list. Also use when the user refers to nvim (e.g. "in nvim", "my nvim") or mentions opened/open files without specifying a path.
