StillHammer 579cadeae8 feat: Complete UIModule Phase 7 - ScrollPanel & Tooltips
This commit implements Phase 7 of the UIModule, adding advanced features
that make the UI system production-ready.

## Phase 7.1 - UIScrollPanel

New scrollable container widget with:
- Vertical and horizontal scrolling (configurable)
- Mouse wheel support with smooth scrolling
- Drag-to-scroll functionality (drag content or scrollbar)
- Interactive scrollbar with proportional thumb
- Automatic content size calculation
- Visibility culling for performance
- Full styling support (colors, borders, scrollbar)

Files added:
- modules/UIModule/Widgets/UIScrollPanel.h
- modules/UIModule/Widgets/UIScrollPanel.cpp
- modules/UIModule/Core/UIContext.h (added mouseWheelDelta)
- modules/UIModule/UIModule.cpp (mouse wheel event routing)

## Phase 7.2 - Tooltips

Smart tooltip system with:
- Hover delay (500ms default)
- Automatic positioning with edge avoidance
- Semi-transparent background with border
- Per-widget tooltip text via JSON
- Tooltip property on all UIWidget types
- Renders on top of all UI elements

Files added:
- modules/UIModule/Core/UITooltip.h
- modules/UIModule/Core/UITooltip.cpp
- modules/UIModule/Core/UIWidget.h (added tooltip property)
- modules/UIModule/Core/UITree.cpp (tooltip parsing)

## Tests

Added comprehensive visual tests:
- test_28_ui_scroll.cpp - ScrollPanel with 35+ items
- test_29_ui_advanced.cpp - Tooltips on various widgets
- assets/ui/test_scroll.json - ScrollPanel layout
- assets/ui/test_tooltips.json - Tooltips layout

## Documentation

- docs/UI_MODULE_PHASE7_COMPLETE.md - Complete Phase 7 docs
- docs/PROMPT_UI_MODULE_PHASE6.md - Phase 6 & 7 prompt
- Updated CMakeLists.txt for new files and tests

## UIModule Status

UIModule is now feature-complete with:
 9 widget types (Panel, Label, Button, Image, Slider, Checkbox,
   ProgressBar, TextInput, ScrollPanel)
 Flexible layout system (vertical, horizontal, stack, absolute)
 Theme and style system
 Complete event system
 Tooltips with smart positioning
 Hot-reload support
 Comprehensive tests (Phases 1-7)
