Graphcheckr 0.1.1 improves store readiness, settings, and metadata auditing polish.

What's new:
- Added an optional setting to open the GitHub changelog after extension updates.
- Added a reusable options page that shares the same settings UI as the popup.
- Added clickable build metadata for version, commit, and branch.
- Added support for displaying all discovered Open Graph preview images instead of only the first image.
- Added per-image preview cards with image labels, metadata badges, and external image-open actions.
- Added hover text for truncated image labels.
- Added browser-store screenshot and promo asset generation for Chrome, Microsoft Edge, and Firefox listing assets.

Changed:
- Settings now use shared components and Pinia-backed state.
- Screenshot generation now uses real browser-extension runs against real websites.
- Store screenshots now include the full real screenshot set for Chrome, Microsoft Edge, and Firefox.
- Store promo artwork is now generic and store-neutral.
- Build info layout is more compact in the popup.
- External-link buttons now use external-link icons consistently.
- Build and project documentation were updated.

Fixed:
- Fixed Open Graph image extraction for repeated og:image and og:image:url entries.
- Improved social image labels by using available image alt text.
- Fixed TypeScript and SonarLint issues in the snapshot parser.
