Module grid 

2D Grid layout system for dashboard-style positioning.

Grid provides constraint-based 2D positioning with support for:

• Row and column constraints
• Cell spanning (colspan, rowspan)
• Named areas for semantic layout references
• Gap configuration

Example

use ftui_layout::grid::Grid;
use ftui_layout::Constraint;
use ftui_core::geometry::Rect;

// Create a 3x2 grid (3 rows, 2 columns)
let grid = Grid::new()
    .rows([
        Constraint::Fixed(3),      // Header
        Constraint::Min(10),       // Content
        Constraint::Fixed(1),      // Footer
    ])
    .columns([
        Constraint::Percentage(30.0),  // Sidebar
        Constraint::Min(20),            // Main
    ])
    .row_gap(1)
    .col_gap(2);

let area = Rect::new(0, 0, 80, 24);
let layout = grid.split(area);

// Access cell by (row, col)
let header_left = layout.cell(0, 0);
let content_main = layout.cell(1, 1);
