feat: -a/-g runtime reading toggle and WRAP config option

- -a/--all and -g/--gospel override the compiled GOSPEL_ONLY default per run;
  the reading text for both is always embedded, so this is free. Flags may
  appear in any position alongside the optional date.
- WRAP config.h option wraps reading text at N columns; 0 (default) fits the
  terminal via TIOCGWINSZ and leaves piped output one line per verse. Greedy,
  space-breaking, UTF-8 aware (continuation bytes do not count as columns).
- Rework arg parsing into a small flag loop; expand -h usage.

No table/data change; OF and EF both build clean under -Wall -Wextra. Binary
grows ~4 KB (666 KB OF). Stays compile-time-first, suckless-style: the only
run-time options are the reading-set toggle and -h.
