feat: add right-click restorer for current site

- Add RightClickRestorer page with active unlock trigger
- Content script with dual-world strategy (isolated + main world)
- Monkey patch preventDefault/stopPropagation via background executeScript
- Overlay penetration for pointer-events blocking layers
- Delegated main-world injection to avoid CSP restrictions
- Async message handling for reliable state updates
- i18n translations (zh/en) and unit tests
