📝 docs(changelog): regenerate CHANGELOG.md for PR #59

[konih]

Summary

• PR docs: record 8 operator rulings from 2026-08-16 session #59's 5 commits (D-144..D-151 operator rulings, ADR amendments, docs-truth cleanup) were never run through `task changelog-write`, leaving CHANGELOG.md drifted from `git-cliff`'s output.
• `hack/release/verify-changelog.sh` is red on `main` @ df77035 as a result — this contaminates every in-flight EX-S05/S06/S08 lane's `task check` with an unrelated failure.

Test plan

• `bash hack/release/verify-changelog.sh` — ok
