7cde6370d8 fix: Sistema de focus rediseñado y funcionando 
Cambios principales:
- Nuevo FocusSystem unificado en core/focus.zig
- Separación registration_group / active_group para multi-panel
- Focus implícito para primer widget del grupo activo
- Table inicializa selected_row/col a 0 cuando tiene datos
- Corregido test navKeyPressed (usaba setKeyState en vez de handleKeyEvent)

Bug resuelto: tabla no respondía a teclado sin clic previo
Causa: selected_col quedaba en -1, selectedCell() retornaba null

Documentación: docs/FOCUS_TRANSITION_2025-12-11.md

9b6210c76e refactor: Unificar sistema de focus - trabajo en progreso 
PROBLEMA DETECTADO:
- Existían dos sistemas de focus paralelos que no se comunicaban
- FocusManager (widgets/focus.zig) usaba IDs u32
- FocusGroupManager (core/focus_group.zig) usaba IDs u64
- Esto causaba que Tab no funcionara y clics no cambiaran focus

SOLUCIÓN CONSENSUADA:
- Usar SOLO FocusGroupManager como fuente de verdad
- Integrar en Context con métodos públicos
- Widgets se auto-registran en el grupo activo al dibujarse
- Tab navega DENTRO del grupo activo
- F6 (u otro) cambia entre grupos/paneles

CAMBIOS:
- context.zig: Añadidos createFocusGroup(), setActiveFocusGroup(),
  hasFocus(), requestFocus(), registerFocusable(), handleTabKey()
- text_input.zig: Usa @intFromPtr para ID único, se auto-registra
- table.zig: Ahora se registra como widget focusable
- widgets.zig/zcatgui.zig: Eliminadas referencias antiguas a FocusManager
- CLAUDE.md: Documentado el trabajo en progreso

ESTADO: EN PROGRESO - Compila pero requiere más testing

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

c4ea6422dc style: Use consistent lowercase naming (zcatgui, not zCatGui) 
Apply TEAM_STANDARDS Norma #25: project names use lowercase
everywhere - repo, directory, module, documentation, imports.

No CamelCase in project names. Consistency = less cognitive friction.
