IHoldByPartition
Interface for hold operations scoped to a specific partition: creation, execution, release, reclamation, and partition-scoped read queries.
Aggregates the holder-facing write operations (previously in IHoldTokenHolder) and the partition-scoped read operations into a single interface. The two global methods — getHeldAmountFor and getHoldThirdParty — are intentionally excluded here and live in IHoldFacet.
