- AllocatedMemory.Read<T>/Write<T>/ReadBytes/WriteBytes now validate that
the requested byte range stays within the allocated block before calling
into the memory accessor.
- Patch.Apply/Remove temporarily changes the target page to read-write and
restores the original protection, mirroring the Detour behavior.
- MainThreadPump.WorkItem uses TrySetResult/TrySetException and swallows the
InvalidOperationException raised when a completion source is already
completed, preventing Dispose from failing during concurrent pump drainage.
Regression tests added for all three fixes.
Tests: 206 passing, 4 skipped.
