Review: cfg for new experimental root hash

Summary: This is a 1-line change that adds "vexp" as a config option mapping to ETHSpareMPTVersion::VExperimental in the live_root_hash_config() match arm. The change itself is correct — VExperimental exists in the enum and is fully wired up in eth-sparse-mpt.

One minor issue flagged inline: the error message on the fallback _ arm still says "can be v1 or v2" and should be updated to include vexp.

No issues found. The previous review's suggestion (updating the error message to include vexp) has been applied in commit 545c7ed. The change is minimal and correct — it adds "vexp" mapping to ETHSpareMPTVersion::VExperimental in the config match arm, and the error message now properly lists all three options.

No issues found. The PR is split into two concerns:

1. Config change (base_config.rs): Adds "vexp" → ETHSpareMPTVersion::VExperimental mapping with updated error message. Clean and correct.

2. Lint suppression (remaining 6 files): Adds #[allow(clippy::result_large_err)] and #[allow(clippy::manual_saturating_arithmetic)] attributes to suppress new clippy warnings. These are reasonable — the result_large_err warnings are on closures/functions where changing the error type would be a larger refactor, and the manual_saturating_arithmetic ones are in block-building context code where the existing checked arithmetic is intentional.

No bugs, security issues, or performance concerns.
