Use Hermes native prompted sessions

Hermes now keeps chat queries interactive and literal to TUI control syntax, so launch it directly and let its own session flow replace the local one-shot, usage-file, and resume bridge.

Gate installation on the capability added with native interactive queries, preserve unowned mise environments, and keep the unprompted launch path unchanged.
