Publishes the TRACE v0.2 conformance cutover.
Breaking: TR-ENV now requires the profile tag:agentrust-io.com,2026:trace-v0.2 and fails a record carrying the v0.1 identifier tag:agentrust.io,2026:trace-v0.1.
The v0.1 URI named agentrust.io, a domain this project never controlled. RFC 4151 permits a tag URI only where the minting authority controlled the named domain on the stated date, so the identifier was invalid rather than misspelled. See agentrust-io/trace-spec#107.
Cutover, not dual acceptance. A conformance suite that passed both identifiers would certify records minted under a domain we do not own, which is the thing being corrected.
If you still emit v0.1 records, stay on 0.3.x. To migrate: update the profile string and bump agentrust-trace to 0.5.0. Nothing else about the record format changed.
