Review of PR #916

• Gather context and read changed files
• Review Makefile changes
• Review benchmark file changes
• Review deleted order_dumper.rs
• Review block_orders/mod.rs changes
• Post review summary

LGTM — this is a clean, straightforward fix. All four changes are correct and well-motivated:

Makefile (--all-targets): Adding --all-targets to both lint and fmt targets ensures clippy catches issues in tests, benches, and examples — not just lib/bin targets. The fmt target also correctly gains --workspace which it was previously missing (the lint target already had it).

Benchmark fix (txpool_fetcher.rs): The subscribe_to_txpool_with_blobs signature was updated upstream to require Arc<MempoolTxsDetector> as the third parameter. The benchmark now passes it correctly. No issues.

order_dumper.rs deletion: OrderDumper and OrderStoreAction are not referenced anywhere else in the codebase — confirmed via grep. The comment "Soon to be replaced my mockall" suggests it was already slated for removal. Clean delete.

block_orders/mod.rs: Simply removes the #[cfg(test)] mod order_dumper; declaration to match the file deletion. No other changes to this file.

No bugs, no security concerns, no performance issues.
