Shared binary-role admission and process-birth identity acquisition. The
host backend supplies exactly one nonblocking OS entropy request; it may
return errors or short counts and must not retry or invent a fallback.
AcquireEntropy reads Destination, Extent and VersionOrFlags (then flags),
returns the actual signed syscall result in Result, and preserves the saved
destination. Load reads a little-endian word relative to Destination.
Other word operations wrap at 64 bits; Compare supplies unsigned ordering.
Register assignment and the syscall ABI belong exclusively to each emitter.
A failed acquisition may have touched bytes. They carry no authority until
the count and every nonzero identity role have passed, returning status zero.
