Adds /handoff <platform> CLI command that queues the current session for
resume on the configured home channel of any messaging platform.
CLI side:
- /handoff telegram — marks session in shared DB, sends summary to
the Telegram home channel via send_message
- /handoff discord — same for Discord
- Supports telegram, discord, slack, whatsapp, signal, matrix
Gateway side:
- On new session creation, checks for pending handoffs for the
incoming message's platform
- If found, loads the CLI session's full conversation history and
injects it into the context prompt as a handoff transcript
- Agent continues the conversation seamlessly
