Consolidate `processor.rs` into `validator.rs`, removing the separate module. Add parallel and overlay-based state root computation via `reth-trie-parallel`, `reth-trie-db`, and `reth-engine-tree`. Introduce `OverlayProviderFactory` trait alias and `compute_state_root` dispatcher that tries parallel SR first and falls back to serial. Replace direct `BlockBuilder` usage with `PayloadProcessor`-based execution using a no-op `flashblock_tx_iterator` for pre-recovered transactions. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Note on subsequent reth version upgrades (todo):
- Add paradigmxyz/reth#22347 fixes once reth version is upgraded
- Add paradigmxyz/reth#22647 optimizations to share tx index
- paradigmxyz/reth#22604

Summary
This PR contains the flashblocks RPC layer revamp optimizations on the execution validation layer, and aligns to the upstream reth's payload validator logic. The old flashblocks RPC worker logic was vastly over-complicated, and this PR revamps the version entirely. Note that the PR is separated from the revamp PR #176 for better clarity on the validation optimizations.
The PR adds the new
FlashblockSequenceValidatorwhich encapsulates the entire flashblocks sequence validation logic. It aligns the sequence validation logic to the highly optimized upstream reth's engine payload validator.Ref: https://github.com/paradigmxyz/reth/blob/main/crates/engine/tree/src/tree/payload_validator.rs
Below are some of the key optimizations:
