openclaw - 💡(How to fix) Fix Telegram/chat surfaces: /sessions list + /resume <id> for past sessions

Problem

On chat surfaces (Telegram in particular), /new archives the current session and starts a fresh one, but there's no in-chat way to see past sessions or resume one. Compare with claude code, where resume lists prior sessions and lets you pick one.

Today the only related primitive is /focus <target>, which binds the current chat to a session id — but you need to already know the id, and there's no list command on Telegram to find it. Session management effectively lives in the Control UI / dashboard, which is a context switch away from the surface you're chatting on.

Proposal

Add a /sessions (or /resume) text+native command on chat surfaces that:

1. /sessions — lists the sender's recent sessions (id, last-active time, short title/first-message preview, model).
2. /sessions resume <id> (or /resume <id>) — rebinds the current chat to that session id (effectively /focus <id> with discoverability).
3. Native button menu on Telegram/Discord where supported, so it's a pick-list rather than typing an id.

Scope: per-sender, respects existing allowlists and session.identityLinks. Archived sessions included; pruned ones excluded.

Why

• Parity with claude code resume UX — common request from users who jump between chat and CLI.
• Reduces dashboard round-trips for a frequent operation.
• Composes nicely with /dock-* for moving the resumed session's reply route.

Workaround today

/focus <id> if you happen to know the id (e.g. from /status or the dashboard). Not discoverable from Telegram.
