[FEATURE] Feature request: in-session /remote-control toggle to enable Remote Control on an already-running session

Problem Statement

Summary

Currently, Remote Control can only be enabled at session start, via the --remote-control CLI flag. There is no way to toggle it on (or off) inside a running session.

Use case

I frequently want to attach my phone to a session that is already in flight — long-running task, full context, lots of files read, partial plans on screen. Today the only path is:

1. Exit the session
2. claude --resume <id> --remote-control
3. Pick the session from the picker, wait for it to rehydrate

This works but is heavy for what is essentially a connectivity toggle, and it forces a context reload every time I want to step away from the desk.

Proposal

Bring back (or add) an in-session slash command:

• /remote-control — enable RC on the current session, print/show the QR + URL
• /remote-control off — disable RC and invalidate the pairing
• /remote-control status — show whether RC is active, current session name, connected device(s)

Same auth/permission model as the CLI flag — no new surface area, just a runtime toggle.

Why it matters

• Mobility without losing context (the whole point of RC for many of us)
• Symmetry with other session features that are already toggleable mid-session (e.g. model, effort, plan mode)
• Lower friction = more people will actually use the mobile app

Environment

• Claude Code v2.1.145
• macOS (darwin 25.5.0)
• Plan: Max (claude.ai OAuth)
