Add auto-enable option for /remote-control

Feature request

Add a way to automatically enable /remote-control on every session start, without having to type it manually each time.

Suggested approaches (any would work)

1. settings.json key: "remoteControl": "always" or "autoRemoteControl": true
2. CLI flag: claude --remote-control that starts an interactive session with remote control already active
3. /config toggle: "Enable Remote Control for all sessions"

Why

Power users who always want remote access (e.g., monitoring sessions from mobile) currently have to type /remote-control at the start of every session and every /resume. There's no way to persist this preference.

What I tried

• Searched settings.json schema — remote key only has defaultEnvironmentId for SSH environments
• Searched CLI flags — no --remote-control option exists
• SessionStart hooks can't invoke slash commands, so a hook-based workaround isn't possible
• The runtime state (isRemoteMode) is not persisted or configurable

Environment

• Claude Code v1.0.33 (CLI, Linux)
