feat: simplify OpenRPC API and reorganize examples

- Simplified RunnerConfig to just name, command, and optional env
- Removed RunnerType and ProcessManagerType enums
- Removed db_path, redis_url, binary_path from config
- Made runner name also serve as queue name (no separate queue param)
- Added secret-based authentication to all runner management methods
- Created comprehensive osiris_openrpc example
- Archived old examples to _archive/
- Updated client API to match simplified supervisor interface
