Summary

• Upgraded direct devDependencies in packages/web-components, including @microsoft/api-extractor to ^7.57.7, @rollup/plugin-commonjs to ^29.0.2, @rollup/plugin-terser to ^1.0.0, @typescript-eslint/eslint-plugin and @typescript-eslint/parser to ^8.57.1, rollup to ^4.59.0, and vite to ^8.0.0
• Kept comparator-range dependencies unchanged: @lit/context (>=1.1.6 <2.0.0) and lit (>=3.3.1 <4.0.0)
• Kept eslint on the latest compatible 9.x release (^9.39.4) because current eslint-plugin-import and eslint-plugin-promise peer ranges do not yet accept eslint@10

Validation

• npm run build (in packages/web-components): passed
• npm run build:types (in packages/web-components): passed
• npm run test (in packages/web-components): fails in tests/popular-products.test.ts against live Relewise API data; 20 tests passed and 1 integration test failed in each browser

Notes

• npm outdated still reports eslint@10.0.3 as latest, but that major cannot be adopted yet without breaking the current ESLint plugin peer graph
• npm outdated also reports peer dependency @relewise/client@2.23.1 as latest; it was not upgraded because the workflow only updates direct dependencies and devDependencies
