Build an unsigned MarketFactory.linkProposals transaction (final Phase B step).
Groups already-on-chain proposals into one event with a master question and image. This is the last step of the batched multi-leg flow (after propose-markets-batch and submit-proposals), and also useful standalone when legs were proposed independently (e.g. by a sports bot). Only the master’s proposer may link; emits the single LinkedProposalsCreated event the indexer and vote page group by.

These are the only two types a session can be established with, so no other value can reach a build-tx route.
