Subject: [PATCH] Remove bundled WDK7 stdint.h compatibility header

The setup action should not inject a CRT polyfill into every consumer's
include path. Bundling stdint.h silently shadows headers and makes
downstream builds depend on an invisible header owned by the action.
Providing a stdint.h shim is the downstream project's responsibility.

- Delete include/stdint.h and the include/ directory
- Drop WDK7_COMPAT_INCLUDE_DIR wiring from the CMake toolchain
- Remove the compatibility-header feature line from README
- Revert the e2e exe fixture to not depend on <stdint.h>
