parity(#143): post-migration span capture + diff vs #137 baseline

Browse Source 
Captured from feature/tracing-migration f510940 (rebased on master 8284509),
same Jaeger / request set / DB snapshot procedure as pre-migration. Result:
names + semantic attributes preserved, traceparent intact, no orphaned spans,
async/streaming paths now single traces. See post-migration/README.md.
