chore: bump eth.zig to v0.8.1

[lukemacauley]

Bumps the eth dependency from v0.8.0 to v0.8.1 (StrobeLabs/eth.zig#104): KMS stale-connection retry, verified broadcast, and real signer-error propagation.

Why this SDK needs the bump

gator-liquidators depends on both this SDK and eth directly. Zig identifies packages by content hash, so if this SDK stays on eth v0.8.0 while gator moves to v0.8.1, gator compiles two different eth copies and the vendored C crypto (secp256k1 / blst / c-kzg) collides with duplicate-symbol link errors. Both must reference the identical eth version to dedupe.

Testing

• zig build — clean
• zig build test — 342/342 pass
• No source changes; the WalletError.SigningFailed removed upstream is unused here.

Follow-up

After merge, tag v0.5.1 so gator can pin it; gator's bump PR references both v0.5.1 and eth v0.8.1.
