Subject: [PATCH] feat(cli): --host flag for headless hosting

Hosting was only reachable through the interactive dialoguer menu; there
was no way to start a host non-interactively. Add a --host flag that runs
host::run directly (interactive=false), bypassing the menu. Useful for
scripting and required by the upcoming --gui front-end, which drives this
binary as a child process. Guards against --host + ticket (contradictory).
