If mine and reorg are anvil-dependent steps, I would suggest renaming them anvil_mine and anvil_reorg.
Add new YAML test step types for anvil-based integration tests: - `anvil` step: validates anvil fixture is available - `mine` step: mines N blocks on anvil chain - `reorg` step: triggers blockchain reorg with specified depth These steps enable writing streaming join tests with dynamically generated blockchain data from anvil. Includes example test spec `streaming-join-anvil.yaml` that tests a self-join on blocks via parent_hash with incremental streaming.
Add test for INNER JOIN between blocks and transactions tables. Returns empty results since mined blocks have no transactions.
Validates that streaming joins correctly handle blockchain reorganizations: - Mine 5 blocks, take initial join results - Trigger reorg (depth 2), mine 3 new blocks - Verify incremental results reflect reorganized chain

Address review feedback: since these steps are anvil-dependent, rename them to make the dependency explicit.
