Bump tycho-simulation and tycho-execution to 0.431.0, which adds native Pons V2 hook simulation for uniswap_v4_hooks on Robinhood. Register gigadex_v3 as a Uniswap V3 fork. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

tycho-simulation 0.431.0 decodes a Uniswap V4 pool whose hook is zero or takes no part in swaps as a plain V4 pool. On 0.428.0 those pools went to the generic VM hook handler and failed to decode, since the recording has no hook contract state. The Ethereum fixture now yields 161 more uniswap_v4 components (683 -> 844); every other protocol is unchanged. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Summary
tycho-simulationandtycho-executionto>=0.431.0(lockfile: all tycho crates 0.428.0 → 0.431.0). 0.431.0 includes feat: add native Pons V2 Uniswap V4 hook support on Robinhood tycho#1489, which adds native simulation for Uniswap V4 pools using the Pons V2 hook on Robinhood (uniswap_v4_hooks). On earlier versions these pools fall back to the generic VM hook handler and fail withAfterSwap/BeforeSwap hook simulation failed.gigadex_v3as a Uniswap V3 fork (UniswapV3State), matching tycho's own registration and the tycho-execution V3 family list. Robinhood prod Tycho now advertises it, and fynd currently logsSkipping unknown protocol: gigadex_v3.uniswap_v4_hooksandgigadex_v3to the Robinhood registration regression test.No fynd code changes are needed for Pons:
