v0.1.2

Governance release for change-set review. This release adds a diagnostic
/harness review workflow so maintainers can challenge current changes before
completion without adding runtime hooks, policy enforcement, CI adapters, or
more automatic installer behavior.

Added

• /harness review command workflow for opposing harness-engineering review of
  the current change set.
• Harness review report template and example report.
• Quick Start, full adoption prompt, localized README, static site, and
  component-map wiring for /harness review.
• Regression tests that keep /harness review command routing, localized docs,
  report-template sections, and prompt drift covered.

Changed

• Clarify that the existing harness review checklist is a periodic maintenance
  checklist, distinct from the /harness review change-set command.
• Update the roadmap from adding /harness review to refining it through real
  target-repository use.
