Function ratatui_end_frame_hashed

#[no_mangle]
pub extern "C" fn ratatui_end_frame_hashed(
    handle: *mut c_void,
) -> *const u8

Like ratatui_end_frame, but skips rasterization when the cell buffer is unchanged from the previous frame (hash-based dirty check). Returns a valid pixel pointer when content changed, or null when unchanged. The previous frame’s pixel buffer remains valid when null is returned.
