Remove a/, p/, sk/, m/, tr/, tmp/, u/, x/, and per-session t/ from the
9P namespace. These are all files on disk that the runtime reads directly
from ~/.config/ollie/ — serving them through 9P added indirection without
value.
What remains:
- /s/ (live sessions: the dynamic state that doesn't exist on disk)
- /backends, /models, /help (synthetic root files)
This brings olliesrv's scope in line with the D-Bus daemon: session
lifecycle, prompt submission, state observation, and streaming output.
