release: prepare v1.0.0

- Bump version to 1.0.0 in package.json and artifacthub-pkg.yml
- Add explicit devDependencies: vitest, @testing-library/react,
  @testing-library/jest-dom, @testing-library/user-event, jsdom,
  react, react-dom, @types/react, @types/react-dom, react-router-dom,
  @mui/material, notistack — resolves phantom-dep test failures
- Add process.env.NODE_ENV define to vitest.config.mts (fixes
  "act() not supported in production builds" failures)
- Switch to pnpm lockfile (pnpm-lock.yaml), drop package-lock.json
- Remove install-plugin.sh (violates ArtifactHub-only install policy)
- Fill in CHANGELOG entries for v0.2.22, v0.2.23, v0.2.24
- Update CHANGELOG [1.0.0] and version comparison links
- All 233 tests pass
