/** Lightweight fixture for fork chain parameter tests.
 *  Uses ChainType::FORK directly via TestingSetup (not TestChain100Setup,
 *  which hardcodes REGTEST).  Fork activation defaults to MTP 1 (active
 *  from the start) with a reduced delay (1024 steps) so tests run fast.
 *  No pre-mined chain — use mineBlocks() if needed.
