Walkthrough

PreferencesSection now exposes a link-preview switch in appearance settings. The switch reads and updates linkPreview through useView. English, UK English, Arabic, and French locales include the link-preview description. The preferences media metadata test now provides the required ViewContext mock.

Greptile Summary

Adds a Preferences switch that controls the existing persisted link-preview setting.

• Connects the new switch to ViewContext so it stays synchronized with the existing memo display control.
• Adds the preference description in Arabic, British English, English, and French, with English fallback for other locales.
• Updates the existing Preferences test mock for the newly consumed context.

Confidence Score: 5/5

The pull request appears safe to merge with no actionable defects identified.

The switch uses the existing shared and persisted link-preview state, all current component render paths provide the required context, and untranslated locales resolve the new description through the established English fallback.

Add coverage for the new link-preview switch.

This mock only allows PreferencesSection to render in the existing media-metadata test. It does not verify that the switch reflects linkPreview or calls setLinkPreview with the updated boolean. Add a focused test that toggles the switch and asserts the mocked setter.
