EllesmereUI增强-Kogotool (EUI_Kogotool)

## New & Changed
- **Extra Frame enhancement: new "Pet" frame**: You can now configure extra text (content / alignment / size / offset / color, etc.) for the pet frame, with its own independent enable toggle like the other frames.
- **Settings adjustments**:
  - Removed the "Nameplates" feature.
  - Moved the "Enhanced Pathing & Tracking" setting from Blizzard UI enhancement to Quest Tracking, and removed the redundant note text in its title.
  - Renamed "Enhanced XP Bar" to "XP / Reputation Bar".
  - Added a "Click frame to quick-mark" toggle to Quick Focus (when disabled, only clicking the target model and nameplates triggers quick focus).

## Bug Fixes
- **Reset damage meter on entering instance**: Entering a new instance now shows a confirmation popup (instead of silently resetting), supporting EllesmereUIDamageMeters, the built-in damage meter, Details!, and Skada; only prompted once per instance.
- **Chat-link hover tooltip**: Fixed the toggle not taking effect immediately — enabling/disabling now applies instantly without a UI reload.
- **Error fix**: Fixed a secret-string related error (taint) when opening the damage meter panel, improving stability.

> Note: Some features require a `/reload` to take effect.
