Implements a KIO worker that maps ollie:///path to the Ollie 9P
namespace. Supports listing, reading, writing, mkdir, delete, and
rename — all operations Dolphin needs for full file manager integration.
Works with both KF5 (RealWorkerFactory) and KF6 (WorkerFactory).
Type ollie:/// in Dolphin's location bar to browse sessions and agents.
