Add reusable certificate and file validation helpers

Fix process-name ownership and module lookup outputs, add explicit SPKI hashing and bounded chain access, and improve WDM integration. Deprecate superseded entry points with migration guidance and align branch code and tests with the library style.

Add CI validation helpers with explicit signature selection and owned results

Document runtime-confirmed CI signer selection and crypto reuse

Expand CI compatibility matrix to twenty verified samples

Extend CI export matrix with Windows 11 x64 and ARM64 samples

Document CI API availability and historical mincrypt layouts

Add explicit Authenticode workflows and correct CI helper contracts

Document CI validation flag 0x20 and add kernel probe

Harden CI digest parsing and failure cleanup
