SpecLens v1.2.0

• Spec checks (beta) - SpecLens now lints changes and specs locally and deterministically: missing documents, malformed EARS/Gherkin blocks, empty or duplicated requirements, RFC 2119 misuse, ambiguous wording. Findings render as IDE-style underlines with hover explanations, plus a new Checks view in the sidebar (group by change or by check type), a resizable results panel scoped to what you're reading, and severity badges across the app. On by default; Settings → General can disable it or opt archived changes in
• Repositories with large git histories load dramatically faster: authorship now comes from a single history walk instead of one per file (a 4,500-commit repo with 2,800 specs went from hanging indefinitely to about 4 seconds)
• Only one right panel (comments, spec checks, AI summary) stays open at a time
• Updated dependencies: Vite 8, TypeScript 7, React plugin 6, js-yaml 5
