chore(release): settle v2.0.18

[mega-maxwell]

Settle v2.0.18 at d644868dbebe2dfd66b56059bf50ad7b7598f42e (tip of release-v2.0.18).

Merging this PR is the settlement decision: release-publish will tag the merge commit as v2.0.18 and publish the GitHub Release with the notes below. The default branch picks this entry up in the next release candidate PR. If more commits land on release-v2.0.18 first, this PR goes stale and must be regenerated.

v2.0.18 (2026-09-08)

Refactoring

• core: remove the unused EIP-3155 trace writer (#195)
• behavior-preserving cleanups and unused-API removals (#194)

CI

Chores

• bump salt to v1.0.6 (#200)

Claude review status

Living comment — rewritten in place. The review workflow keeps this single comment up to date instead of posting a new one each round, so it always describes the latest reviewed commit and the earlier text is intentionally gone. No reply is needed here; reply to a finding in its own review thread, and answer an open question in a reply on this PR. The next review round reconciles your answer.

Resetting the 2.0.18 release to a clean state so it can be run from scratch on the current pipeline; the candidate merge (#202) is being reverted on main and release-v2.0.18 removed.
