Functions
Value	nk::builtin::sprintf (const Value &fmt, Span< const Value > args, std::pmr::memory_resource *mr=nullptr)
	Formats data into a character array or string according to format specifier fmt (sprintf(fmt, ...)).
std::string	nk::builtin::sprintf (const std::string &fmt, Span< const Value > args, std::pmr::memory_resource *mr=nullptr)
	Formats data into a C++ string according to format string fmt.
std::string	nk::builtin::dispFormat (const Value &a)
	Formats Value for terminal display via disp.
void	nk::builtin::disp (const Value &v, std::ostream &os=std::cout)
	Displays value to the standard output or specified stream (disp(v)).
int	nk::builtin::fprintf (std::ostream &os, const std::string &fmt, Span< const Value > args, std::pmr::memory_resource *mr=nullptr)
	Formats and writes data to an output stream (fprintf(os, fmt, ...)).
Value	nk::builtin::sscanf (const std::string &str, const std::string &fmt, std::pmr::memory_resource *mr=nullptr)
	Reads formatted data from a string according to format specifier fmt (sscanf(str, fmt)).
void	nk::builtin::sscanf (Span< const Value > args, size_t nargout, Span< Value > outs, std::pmr::memory_resource *mr=nullptr)
	Reads formatted data from a string with multi-output support ([A, count, errmsg, nextindex] = sscanf(...)).

Detailed Description

Formatted text I/O and display builtins.

Provides clean, engine-free C++ API for formatted string generation (sprintf), stream printing (fprintf, disp), and text parsing (sscanf, textscan).
