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

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.
