Alan Tse 15bc3fce1a fix(mcp): lock Worker reads vs receive thread ...

Every Worker-reading Python binding except save_worker() read
m_data's zones/plots/threads/etc. without taking
Worker::ObtainLockForMainThread(), racing the live receive thread
that mutates the same structures. This matches
alandtse/tracy#2: crashes only ever hit live instances, never
file-loaded ones (no concurrent writer there), and cluster right
after a big save_trace when the receive thread is catching up on
backlog.

Routes every Worker accessor through a new locked() wrapper using
the same cooperative lock TracyView.cpp already takes once per
frame, so reads can't race live writes without introducing new
stalls on the profiled client.
