/// Guides the user through:
/// 1. Detecting potential workers from SSH config
/// 2. Selecting which hosts to use as workers
/// 3. Probing hosts for connectivity
/// 4. Deploying rch-wkr binary to workers
/// 5. Synchronizing Rust toolchain
/// 6. Starting the daemon
/// 7. Installing the Claude Code hook
/// 8. Running a test compilation
