Add the shared validator-authorized undelegation path backed by DelegationState. Return account ownership in place through the existing owner callback contract, verify the restored bytes and lamports, and close temporary state to its rent payers. Carry allow_undelegation through challenge commitments and add focused tests for paused-cluster exits, callback seed encoding, requester validation, allocation limits, and challenge finalization.

Use a visible top-level heading for the summary prompt.
<Brief summary> is parsed as an HTML element, so the prompt text is not visible. The repository also enables markdownlint, whose default MD041 rule requires a top-level heading.

Synchronize validator undelegation with DelegationState.
Challenge finalization writes UndelegationRequester::Validator only to DelegationMetadataFast. It does not receive or update the v2 DelegationState account. The v2 process_undelegate reads DelegationState.undelegation_requester() and returns NotUndelegatable when it is None.
apply_commit_finalize updates DelegationState, but its only callers are the Direct finalization instructions. Update Challenge finalization to persist the requester in DelegationState, then add an end-to-end test that proposes, approves, finalizes, and undelegates with allow_undelegation = true.
