clean: silence strict -Wsign-conversion / -Wunused-function

Make the build clean under -Wconversion -Wsign-conversion and -Wunused-function
(beyond the Makefile's -Wall -Wextra), so it compiles warning-free on stricter
setups and other compilers: size_t for the verse-index counters in load_text,
a cast in the LZSS matcher, and lz_unpack marked inline (it is unused in the
packer-only mktext translation unit). No behaviour change; packed output is
byte-identical.
