release 0.5.1

[mazong1123]

Release 0.5.1

Changes

• InjectorPP::new_global() constructor — opt-in global (0.4.0-style) code patching that makes fakes visible to all threads, including background threads, timers, and thread pools like rayon.
• Fix: Fakes not visible from rayon worker threads and background timer threads (fixes Mocking not working when used with rayon::join #121).
• Fix: IAT thunk resolution in PatchGuard path on Windows x86_64.

Migration from 0.5.0

If you have tests that broke in 0.5.0 because faked functions are called from background threads (rayon, timers, etc.), change InjectorPP::new() to InjectorPP::new_global():

// Before (0.5.0 — fakes not visible to background threads)
let mut injector = InjectorPP::new();

// After (0.5.1 — fakes visible to all threads)
let mut injector = InjectorPP::new_global();

new() remains the default for thread-local dispatch with parallel test execution. new_global() acquires an exclusive lock, serializing tests that use it.
