Implements VirtualQueryEx + MEMORY_BASIC_INFORMATION wrappers, the immutable MemoryRegion record, the ProtectionScope disposable helper, and MemoryBase.QueryRegion/EnumerateRegions/ChangeProtection. Closes section 1 of add-thread-region-finder.
Because DllInjector enforces matching host/target bitness, a 32-bit caller
always handles a 32-bit target. The correct API is native
GetThreadContext/SetThreadContext with Context32; the Wow64 APIs are only for
64-bit processes inspecting WOW64 targets, which never happens here.
- Collapse the 32-bit path to always use GetThreadContext/SetThreadContext.
- Remove the now-unused Wow64GetThreadContext/Wow64SetThreadContext
declarations.
- Update Context32 doc comment to describe the x86 usage.
- ExternalReader access guard now also accepts QueryLimitedInformation.
Tests: 207 passing, 4 skipped.
- Add GetThreadContext/SetThreadContext overloads accepting Context32 so a
32-bit process on a native 32-bit OS can capture x86 thread context.
- DllInjector.InjectWithThreadHijack now selects the context API based on
both process bitness and OS bitness:
* 64-bit process -> native 64-bit context
* 32-bit process on 64-bit OS -> WOW64 context
* 32-bit process on 32-bit OS -> native x86 context
- ExternalReader now validates that the caller supplied
ProcessAccess.QueryInformation, and surfaces any IsWow64Process failure
instead of silently falling back to host bitness.
Tests: 207 passing, 4 skipped.
