This PR adds minimal Windows AppHelp cache-control support. Note that this is a cacheless AppHelp implementation with some TODO left.

Handle apphelp cache control
09eba89
Implement NtApphelpCacheControl for the startup apphelp cache path, including the live LookupCdb service class.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
@CvvT
Implement cacheless NtApphelpCacheControl contract
cbb79d6
Model Apphelp cache lookup services as STATUS_NOT_FOUND and keep stateful cache operations unsupported in the Windows shim. Move the AHC service class enum into litebox_common_windows and expose STATUS_NOT_FOUND for the externally grounded cache-miss contract.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
@CvvT
Model Apphelp LookupCdb output contract
f715b58
Add a typed Win11 AHC service-data layout for the live LookupCdb path and match the host-observed class-6 contract: validate a 4-byte output slot, write the empty result, and return STATUS_SUCCESS while leaving unprobed Apphelp classes unsupported.

This PR adds minimal Windows AppHelp cache-control support. Note that this is a cacheless AppHelp implementation with some TODO left.

Handle apphelp cache control
09eba89
Implement NtApphelpCacheControl for the startup apphelp cache path, including the live LookupCdb service class.

@CvvT
Implement cacheless NtApphelpCacheControl contract
cbb79d6
Model Apphelp cache lookup services as STATUS_NOT_FOUND and keep stateful cache operations unsupported in the Windows shim. Move the AHC service class enum into litebox_common_windows and expose STATUS_NOT_FOUND for the externally grounded cache-miss contract.

@CvvT
Model Apphelp LookupCdb output contract
f715b58
Add a typed Win11 AHC service-data layout for the live LookupCdb path and match the host-observed class-6 contract: validate a 4-byte output slot, write the empty result, and return STATUS_SUCCESS while leaving unprobed Apphelp classes unsupported.
