* feat: add configurable hover jump navigator delay

- Added `hover_jump_navigator_delay` to Verge config defaults, patch flow, and response payload for persistent app-wide settings.
- Made proxy navigator respect configurable delay via `DEFAULT_HOVER_DELAY` and new `hoverDelay` prop.
- Threaded stored delay through proxy list so hover scrolling uses Verge-configured value.
- Added "Hover Jump Navigator Delay" control in Layout settings with clamped numeric input, tooltip, and toggle-aware disabling.
- Localized new labels in English, Simplified Chinese, and Traditional Chinese.
- Extended frontend Verge config type to include delay field for type-safe access.
