init-cyberlegion

Use this skill to set up or onboard cyberlegion in this session or repo — probe the environment, register the mail-surfacing hook, and (in a root session, on your yes) bind this pane as the durable legate owner inbox. Triggers: 'set up cyberlegion', 'onboard the legion', 'register the cyberlegion surfacing hook', 'make this pane my main legion inbox', 'get cyberlegion working in this repo'. Not for spawning/messaging/dispatching a peer (that is legate), reading or acking owner mail (that is manage-inbox), or unrelated init like a git repo, npm package, or commit discipline.
