El clip se aplicaba solo al área de contenido (excluyendo header),
lo que permitía que el texto de los headers se extendiera fuera
de los límites de la tabla.
Ahora el clip abarca toda la tabla (bounds completos) antes de
dibujar headers y contenido.

Table clipping:
- Add clip region around table content area
- Prevents cell text from drawing outside table bounds
- Header and scrollbar render outside clip region
Cursor animation API:
- Add CURSOR_IDLE_TIMEOUT_MS (5s) and CURSOR_BLINK_PERIOD_MS (500ms) constants
- Add needsCursorAnimation() to check if cursor should blink
- Add getAnimationTimeout() for dynamic event loop timeout
- Update TextInput to use constants from Context
The application can now query ctx.getAnimationTimeout() to determine
if a short timeout is needed for cursor animation, or if it can wait
indefinitely for events.

textarea/ (was 882 lines):
- types.zig: TextAreaConfig, TextAreaColors, TextAreaResult
- state.zig: TextAreaState with cursor/selection methods
- render.zig: drawLineNumber, drawLineText, drawLineSelection
- textarea.zig: Main API with re-exports and tests
progress/ (was 806 lines):
- render.zig: Shared drawing helpers (stripes, gradients, arcs)
- bar.zig: ProgressBar widget
- circle.zig: ProgressCircle widget
- spinner.zig: Spinner widget with animation state
- progress.zig: Main API with re-exports and tests

Split the 1770-line table.zig into a cleaner module structure:
src/widgets/table/
├── table.zig (~400 lines) - Public API + re-exports + tests
├── types.zig (~150 lines) - Enums, configs, column definitions
├── state.zig (~500 lines) - TableState, TableResult
├── keyboard.zig (~270 lines) - Keyboard handling, search
└── render.zig (~350 lines) - Drawing functions
Benefits:
- Each file is now manageable (<500 lines)
- Clearer separation of concerns
- Easier to navigate and modify
- Same public API (no breaking changes)

Phase 1: Frame timing in Context
- Added current_time_ms and frame_delta_ms to Context
- Added setFrameTime() method for applications to provide timing
Phase 2: Centralized shortcuts system
- Added StandardShortcut enum with common shortcuts (copy, paste, etc.)
- Added isStandardActive() function for checking shortcuts
- Updated TextInput to use centralized shortcuts
Phase 3: Incremental search in table
- Added search_buffer, search_len, search_last_time to TableState
- Added addSearchChar(), getSearchTerm(), clearSearch() methods
- Typing in focused table searches first column (case-insensitive)
- 1 second timeout resets search buffer
Phase 4: Blinking cursor in TextInput
- Cursor blinks every 500ms when field is focused
- Uses current_time_ms from Context for timing

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

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

- Add clearRect as verified feature
- Mark fillRect as improved with SIMD @memset
- Add historial entry: render 1.4ms → 1.0ms

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
For solid colors (alpha=255), use @memset per row instead of
pixel-by-pixel loop. @memset is SIMD-optimized by the compiler
(uses SSE/AVX on x86-64).
Result: Render time 1.4ms → 1.0ms (28% faster in Release build)
Also cleaner code separation between solid color fast path
and alpha blending slow path.

Framebuffer:
- Add clearRect() for clearing specific rectangular regions
SoftwareRenderer:
- Add executeWithDirtyRegions() for optimized partial rendering
- Add clearRect() convenience method
- Add commandBounds() to extract bounding box from draw commands
- Add rectsIntersect() helper for intersection testing
This enables applications to:
1. Clear only dirty regions instead of full screen
2. Skip rendering commands outside dirty areas
3. Significantly reduce CPU when only small areas change
Usage: Pass dirty_regions from Context.getDirtyRects() to
executeWithDirtyRegions() instead of using clear()+executeAll().

- Add waitEvent() and waitEventTimeout() to Backend abstract interface
- Implement SDL_WaitEvent and SDL_WaitEventTimeout in SDL2 backend
- Refactor translateEvent into shared function
- Optional vtable entries with fallback to pollEvent for compatibility
This enables progressive sleep patterns:
- Phase 1: Short sleep (8ms) for quick response
- Phase 2: Medium sleep (33ms) for moderate idle
- Phase 3: SDL_WaitEventTimeout for 0% CPU in deep idle
Result: CPU 92% → 1.9% in idle applications.

Cambio de SDL_RENDERER_SOFTWARE a SDL_RENDERER_ACCELERATED | PRESENTVSYNC:
- VSync sincroniza con el refresco del monitor (~60Hz)
- SDL_RenderPresent() ahora bloquea hasta el próximo frame
- Elimina necesidad de sleep manual en aplicaciones
- CPU de ~70% a ~1-5% en idle
Fallback a software renderer si GPU no disponible.

El widget TextInput ahora procesa internamente:
- Backspace/Delete: borrar caracteres
- Flechas izq/der: mover cursor
- Home/End: inicio/fin del texto
- Shift+movimiento: selección
- Ctrl+A: seleccionar todo
- Enter: submit
Esto hace que el widget sea auto-contenido y reutilizable,
sin requerir manejo de teclas en la aplicación.

El renderer iteraba byte por byte, causando que caracteres UTF-8
multi-byte (como ñ, á, é) se mostraran incorrectamente.
Cambios:
- Decodificación completa de UTF-8 (1-4 bytes)
- Mapeo de codepoints a Latin-1 para renderizado
- Caracteres fuera de Latin-1 se muestran como '?'
Esto permite mostrar correctamente texto en español y otros
idiomas europeos que usan caracteres Latin-1.
