Guillaume Ballet 4f6219d5e7 params, core: add binary transition registry + UBT transition-tree end time ... Introduce `params.BinaryTransitionRegistryAddress` (0x1622...1622), the system contract that exposes MPT-to-binary transition state via fixed storage slots (started, conversion progress, ended, base root). Add `ChainConfig.UBTTransitionEndTime *uint64` and the `UBTTransitionActive(num, time)` helper. While UBT is active and the header time is below the configured end (or no end is configured), state access is wrapped in a TransitionTrie that overlays the binary trie on the frozen MPT base; once headers cross this timestamp, the wrapper is dropped. Mirrors the threshold semantics of TerminalTotalDifficulty. Surface the new field in `ChainConfig.String` and the description banner, and add `ChainOverrides.OverrideUBTTransitionEnd` so the value can be patched at startup alongside `OverrideUBT`. No behaviour change yet: callers are introduced in the following commits.		2026-04-29 16:16:54 +02:00
