i think you can compile a static version. but it neeeds some tweaking
and makefile-magic.

DOS is not Linux nor VT-100 emulator. %-) use int 10h or direct memory
access (yes, you need to write a C module for this %-).

and again you can use Video BIOS API (int 10h) or direct memory access.
or install ANSI.SYS. %-) but you'd better write C module. %-)

regarding your question about keyboard handling: int 16h. %-)

i'm not an expert in DJGPP and don't know much 'bout it's standard
libraries, but i bet you can found something in internet. from simple
things like "write colored character and read a key" to complete window
systems. exporting their functionality to Lua should be trivial.
