PTY relay freezes prompt_toolkit after the first turn. Prefer a detached
tmux session, send short kickoff via send-keys, then attach. Keep PTY
as fallback when tmux is missing.
Long kickoff text tripped Hermes paste-collapse ([Pasted text #N]) and
broke Enter handling. Use a short single-line kickoff, inject once after
skill activation, and set raw mode so input stays inside Hermes.
TUI HERMES_TUI_QUERY races session creation (~4s) and often never
submits. Default launcher now uses hermes chat --cli plus a small
Python PTY that injects the Phase-1 kickoff after ready markers.
