[BUG] Slash commands (e.g. /clear) are sent as prompts in Remote Control sessions

What's Wrong?

When using Claude Code via Remote Control (claude remote-control), slash commands like /clear, /compact, /help etc. are not intercepted locally. Instead, they are sent as plain text prompts to the model, which interprets them as natural language.

What Should Happen?

The /clear command should clear the conversation context, same as in a local terminal session.
