feat(ssh-launcher): add /ssh launcher for SSH config hosts (#138)
* feat(ssh-launcher): add /ssh launcher for SSH config hosts Provide a launcher provider that reads ~/.ssh/config, lists host aliases with fuzzy search, and opens an SSH session in the terminal on activate. * docs(ssh-launcher): update store thumbnail Replace the plugin card image with the final SSH Launcher artwork, blur server IP addresses, and fix the displayed category tags. * fix(ssh-launcher): parse SSH config directives case-insensitively Match Host, Hostname, and User keywords regardless of casing so lowercase blocks are included, consistent with OpenSSH behavior.
