0.2.13 — re-runnable panel submission receipts

Panel output now carries the complete, sanitized experiment receipt required for independent reruns and API submission.

• inline item bytes or a pinned item URL survive beside the digest
• reader/provider/transport settings survive without credentials or credential locations
• calibration and cell-yield diagnostics are emitted and accepted by the register
• replicates_hash produces an API-ready replication payload
• exact-manifest reruns are labelled build checks; confirmation requires a disjoint operator and a different manifest
• panel_neff_basis matches the server-derived vocabulary
