BlackMark 30eccf749d Apply clang-format across the whole tree
Run clang-format (the repo's .clang-format: LLVM base, 120 cols, tabs,
Allman functions) over every source file so the tree is formatter-clean.
Whitespace only -- no behavior change; full x64 + x86 suites pass.

Also set SortIncludes: false in .clang-format. Windows include order is
load-bearing (windows.h must precede tlhelp32.h / mmreg.h / xinput.h /
dinput.h; winsock2.h must precede windows.h), and the default
alphabetical sort reorders tlhelp32.h ahead of windows.h -- a build
break. Leaving order alone keeps the manual, correct grouping.

// Unit test for the keyed-mutex acquire decision behind SharedTextureSource::update()
// (host/src/capture/keyed_mutex.hpp). The bug: AcquireSync returning WAIT_ABANDONED -- a prior owner
// (e.g. a host that crashed mid-acquire) died holding the mutex, which GRANTS us ownership -- was
// treated as failure, so the host skipped the frame AND never released, freezing the mirror forever.
// The predicate must treat WAIT_ABANDONED as "acquired" (copy + release) while still rejecting the
// real "didn't get it" cases. Deterministic; no D3D device.
