Ubuntu 0bae727a26 Add attribute governance design: controlled attribute lists, egress regex selection, ingest signature validation ...

Defines the SA-V3-Ext/Int placeholder attribute scheme (external list
owned by the S3 handover spec, internal list for SA routing + internal
S3 usage), the per-egress Regex property for packing/signing selection,
the inverse-regex delete step at true external egress, optional
ingest-time signing with mandatory validation when already signed, and
the S3 JSON-fallback size attribute for suffix-range trailer reads.
