…dangling prune A routingNode collapsed at collapseLevel was Save()d but never sent to createdChan, so collectDeleteAndCreated could not remove it from the deferred delete set; DeleteNodes() then pruned a node the new root still references, surfacing as 'pebble: not found' on GetPath/referencepath after delete churn. Add createdChan <- n.Hash() in the collapse branch. Adds regression test TestCommitCollapsePruneDangling (fails pre-fix, passes post-fix).

Collapsed routing node at collapseLevel was Save()d but never sent to createdChan, so collectDeleteAndCreated couldn't drop it from the deferred-delete set; DeleteNodes() then pruned a node the new root still references -> 'pebble: not found' on GetPath/referencepath after delete churn (StorageV2 blobbers). One-line fix + regression test TestCommitCollapsePruneDangling (fails pre-fix, passes post-fix). Diagnosis: 0chain/blobber docs/wmpt-collapse-prune-dangling.md.
