fix: restrict yaml suffix resolution to externalServiceRegistrations directory @W-20424423@

The decomposeExternalServiceRegistrationBeta preset registered `.yaml`
as a global suffix, causing all .yaml files to be inferred as
ExternalServiceRegistration regardless of location. The fix adds
`strictDirectoryName: true` to the yaml child type and refines the
suffix-based resolution guard to only reject types when the file is
NOT in the expected directory.
