Function ghostty_paste_is_safe 

pub unsafe extern "C" fn ghostty_paste_is_safe(
    data: *const c_char,
    len: usize,
) -> bool

Check if paste data is safe to paste into the terminal.

Data is considered unsafe if it contains:

• Newlines (\n) which can inject commands
• The bracketed paste end sequence (\x1b[201~) which can be used to exit bracketed paste mode and inject commands

This check is conservative and considers data unsafe regardless of current terminal state.

@param data The paste data to check (must not be NULL) @param len The length of the data in bytes @return true if the data is safe to paste, false otherwise
