0cdd44b8a0 fix: TTF ABGR format + herramienta diagnóstico cmap 
Cambios:
- ttf.zig: Fix formato pixel ABGR (era RGBA invertido)
- cmap_debug.zig: Herramienta diagnóstico tabla cmap
- build.zig: Target cmap-debug para ejecutar diagnóstico
- docs/research/TTF_DEBUG_SESSION: Documentación sesión debug

Nota: El código base TTF funciona (cmap_debug lo confirma).
El bug de rendering sigue sin resolver en integración.

105e3c63d1 fix: UTF-8 support in TTF drawText 
- drawText now decodes UTF-8 codepoints instead of iterating bytes
- Fixes rendering of accented characters (á, é, í, ó, ú, ñ, etc.)
- Uses std.unicode.utf8ByteSequenceLength + utf8Decode
- Invalid UTF-8 sequences are gracefully skipped

222c4e1542 fix: DroidSans reemplaza AdwaitaSans (variable) + Y-flip TTF 
- AdwaitaSans era fuente variable (fvar/gvar) incompatible con parser
- DroidSans.ttf: fuente estática 187KB (Apache 2.0)
- Y-flip en rasterización: TTF Y crece arriba, bitmap Y crece abajo
- Pendiente: UTF-8 multibyte en drawText

8adc93a345 feat: zcatgui v0.6.0 - Phase 1 Optimization Complete 
Performance Infrastructure:
- FrameArena: O(1) per-frame allocator with automatic reset
- ObjectPool: Generic object pool for frequently allocated types
- CommandPool: Specialized pool for draw commands
- RingBuffer: Circular buffer for streaming data
- ScopedArena: RAII pattern for temporary allocations

Dirty Rectangle System:
- Context now tracks dirty regions for partial redraws
- Automatic rect merging to reduce overdraw
- invalidateRect(), needsRedraw(), getDirtyRects() API
- Falls back to full redraw when > 32 dirty rects

Benchmark Suite:
- Timer: High-resolution timing
- Benchmark: Stats collection (avg, min, max, stddev, median)
- FrameTimer: FPS and frame time tracking
- AllocationTracker: Memory usage monitoring
- Pre-built benchmarks for arena, pool, and commands

Context Improvements:
- Integrated FrameArena for zero-allocation hot paths
- frameAllocator() for per-frame widget allocations
- FrameStats for performance monitoring
- Context.init() now returns error union (breaking change)

New Widgets (from previous session):
- Slider: Horizontal/vertical with customization
- ScrollArea: Scrollable content region
- Tabs: Tab container with keyboard navigation
- RadioButton: Radio button groups
- Menu: Dropdown menus (foundation)

Theme System Expansion:
- 5 built-in themes: dark, light, high_contrast, nord, dracula
- ThemeManager with runtime switching
- TTF font support via stb_truetype

Documentation:
- DEVELOPMENT_PLAN.md: 9-phase roadmap to DVUI/Gio parity
- Updated WIDGET_COMPARISON.md with detailed analysis
- Lego Panels architecture documented

Stats: 17 widgets, 123 tests, 5 themes
