v0.5.0

• Improve interactive first-contact guidance: the bare dispatcher now offers
  one consent-gated next action after each completed routed command, doctor
  groups repeated actionable findings into recommendations, the upgrade menu
  explains its keep/adopt-all/customize choices, and the dispatcher starts
  with a neutral agent-profile wordmark. Interactive fixture differences are
  limited to those new follow-up prompts, doctor recommendation lines, upgrade
  labels/hints/note, and the neutral dispatcher wordmark; non-interactive
  doctor and upgrade output and JSON remain unchanged.
