feat(gateway): live-stream /update output + interactive prompt buttons (#5180)
* 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. * feat: interactive buttons for update prompts (Telegram + Discord) Telegram: Inline keyboard with ✓ Yes / ✗ No buttons. Clicking a button answers the callback query, edits the message to show the choice, and writes .update_response directly. CallbackQueryHandler registered on the update_prompt: prefix. Discord: UpdatePromptView (discord.ui.View) with green Yes / red No buttons. Follows the ExecApprovalView pattern — auth check, embed color update, disabled-after-click. Writes .update_response on click. All platforms: /approve and /deny (and /yes, /no) now work as shorthand for yes/no when an update prompt is pending. The text fallback message instructs users to use these commands. Raw message interception still works as a fallback for non-command responses. Gateway watcher checks adapter for send_update_prompt method (class-level check to avoid MagicMock false positives) and falls back to text prompt with /approve instructions when unavailable. * fix: block /update on non-messaging platforms (API, webhooks, ACP) Add _UPDATE_ALLOWED_PLATFORMS frozenset that explicitly lists messaging platforms where /update is permitted. API server, webhook, and ACP platforms get a clear error directing them to run hermes update from the terminal instead. ACP and API server already don't reach _handle_message (separate codepaths), and webhooks have distinct session keys that can't collide with messaging sessions. This guard is belt-and-suspenders.
