Bug Description

Support for Zig 0.16.0 is missing, despite what is stated in the README.md file.
There are a lot of errors when trying to compile any example from the examples directory. When reviewing the code, for example in the src/app.zig file, constructs that are not supported in version 0.16.0 are found. And there are a lot of such cases.

Steps to Reproduce

1. zig init
2. zig fetch --save git+https://github.com/muhammad-fiaz/tui.zig.git
3. Add library tui to build.zig by instructions in README.md
4. Copy content from file examples/demo.zig to your src/main.zig
5. zig build

Expected Behavior

I expected the compilation to be error‑free and for the example to work correctly.

Minimal Reproducible Code

const std = @import("std");
const tui = @import("tui");

const Demo = struct {
    fn render(ctx: *tui.RenderContext) void {
        var sub = ctx.getSubScreen();
        sub.clear();
        sub.putStringAt(0, 0, "TUI.zig Demo\n\nExamples available in the examples/ directory. Use the demo runner to start them individually.");
    }
};

pub fn main(init: std.process.Init) !void {
    const io = init.io;

    var app = try tui.App.init(io, .{});
    defer app.deinit();

    const root = Demo{};
    try app.setRoot(&root);
    try app.run();
}
