• Added schema versioning, so updating the app will not lose qvd history unless the schema changes.

PR checklist

Checklist:

• Is the name of this app/solution still App Analyzer?
• Have you updated the version tag in each .qvf file, and followed semantic versioning (e.g. v1.1.1)?
• Is this PR named appropriately? For example:
  • Feature release: feat: add sheet usage event
  • Bug fix: fix: replaced deprecated events
  • Documentation update: docs: updated images in install guide
• Have you reviewed the unbuilt diff generated by the workflow in /diff?

If you wish to merge and release:

• Have this PR approved by a code owner, then merge into main
• Go to releases, an action will generate a draft release with all files in /assets, and any external assets references in release.json
• Make any updates, then submit the release

Common issues:

• After merging, draft release doesn't update - this is usually because
  the action failed due to an old draft release with the same name.
  Delete the draft release, and re-run the action.
