/// OSIRIS Runner
/// 
/// A standalone runner for executing OSIRIS Rhai scripts.
/// Can run in script mode (single execution) or daemon mode (continuous).
/// 
/// Usage:
/// ```bash
/// # Script mode
/// cargo run --bin runner -- runner1 --script "let note = note('test').title('Hi'); put_note(note);"
/// 
/// # Daemon mode (requires runner_rust infrastructure)
/// cargo run --bin runner -- runner1 --redis-url redis://localhost:6379
/// ```
