Summary

Version bump only, from 0.8.12 to 0.8.13. No merge, tag, GitHub release, or npm publish.

• package.json version is 0.8.13.
• package-lock.json top-level version and packages[""].version are 0.8.13. npm version 0.8.13 --no-git-tag-version changed only those two lockfile fields; dependency entries are unchanged.
• CHANGELOG.md adds ## [0.8.13] - 2026-10-30 for #55: structural mandate label variants (Principal mandate (verbatim):, Mandate:, User mandate:, Principal instruction:), unified section boundaries (ASCII space/tab only, fail-closed), CommonMark-conformant fence closing, literal mandate comparison, MANDATE_CONFLICT forces HOLD, and action/tool content cannot weaken the mandate decision.
• The notes for that change had been appended under ## [0.8.12] - Unreleased by the fix(plv): recognize structural mandate label variants #55 merge. They now live under 0.8.13. The 0.8.12 heading is dated 2026-10-10.
• No hardcoded 0.8.12 package-version constants in src/. The CLI reads its version from package.json.

Base is 280211cc36e92e96c337f0d5b3bcb436fe8f8bc5 (fix(plv): recognize structural mandate label variants (#55)).
