Replace StreamFsm and NinePConnection (QProcess-based) with NativeStreamer
which uses the new libollie9p streaming API (open/read_fid/close_fid).
All 9P operations now go through the native library:
- Chat, statewait, eventwait streams use threaded NativeStreamer
- Request/response operations use Lib9pClient directly
- No more subprocess spawning for any 9P operation
Remove ninepBin, ollie9pBin, serverAddr, run9p helper functions.
Remove streamfsm.cpp/h, ninepconnection.cpp/h from build.
Replace subprocess spawning (run9p) with native 9P connection for hot paths:
- refreshSessions() - called on every sessionsChanged event
- loadRootBackends() - called on daemon connect
- loadRootAgents() - called on daemon connect
Lib9pClient wraps the Go shared library with a Qt-friendly C++ API.
Connection persists across operations, eliminating ~2-5ms per-call
process spawn overhead.
Requires libollie9p.so from parent repo's lib9p/ package.
