Teknium 3d698ba4e1 feat(gateway): live-stream /update output + forward interactive prompts
Adds real-time output streaming and interactive prompt forwarding for
the gateway /update command, so users on Telegram/Discord/etc see the
full update progress and can respond to prompts (stash restore, config
migration) without needing terminal access.

Changes:

hermes_cli/main.py:
- Add --gateway flag to 'hermes update' argparse
- Add _gateway_prompt() file-based IPC function that writes
  .update_prompt.json and polls for .update_response
- Modify _restore_stashed_changes() to accept optional input_fn
  parameter for gateway mode prompt forwarding
- cmd_update() uses _gateway_prompt when --gateway is set, enabling
  interactive stash restore and config migration prompts

gateway/run.py:
- _handle_update_command: spawn with --gateway flag and
  PYTHONUNBUFFERED=1 for real-time output flushing
- Store session_key in .update_pending.json for cross-restart
  session matching
- Add _update_prompt_pending dict to track sessions awaiting
  update prompt responses
- Replace _watch_for_update_completion with _watch_update_progress:
  streams output chunks every ~4s, detects .update_prompt.json and
  forwards prompts to the user, handles completion/failure/timeout
- Add update prompt interception in _handle_message: when a prompt
  is pending, the user's next message is written to .update_response
  instead of being processed normally
- Preserve _send_update_notification as legacy fallback for
  post-restart cases where adapter isn't available yet

File-based IPC protocol:
- .update_prompt.json: written by update process with prompt text,
  default value, and unique ID
- .update_response: written by gateway with user's answer
- .update_output.txt: existing, now streamed in real-time
- .update_exit_code: existing completion marker

Tests: 16 new tests covering _gateway_prompt IPC, output streaming,
prompt detection/forwarding, message interception, and cleanup.
