feat(api): retrieve stored temporal-context requests by extra-segment GET

CHANGELOG.d/temporal-context-stored-request-get.md

@@ -0,0 +1 @@
+- `GET /v1/temporal-context/{idempotency_key}/request` returns the stored LineageWeave temporal-context create request on `tepp-loopback` (ADR 0091). Metric-free of RMSE/`tepp.scientific_acceptance.v1`. `inference_status` on the live projection remains `temporal_association_only`. Naruon refused. `NaruonLiveService` stays POST-only. Does not re-open collection GET or cancel lineages. Not GAP-010 Figma/export, not persistence.
