clectio: tiny suckless C daily readings, all readings compiled in

clectio prints the Catholic liturgical day and its Mass readings for a date
with a single table lookup -- no computation, config file, network, or deps
beyond libc. The calendar, reading citations and scripture text are all
compiled in; the whole shipped package fits on a 1.44 MB floppy (~1.29 MiB)
and the binary is ~0.9 MB (OF) / ~0.3 MB (EF).

- suckless config.h: FORM_OF/FORM_EF, SIGLA_ENGLISH/SIGLA_LATIN, COLOR.
- Bring your own Bible: `make CORPUS=mybible.tsv` recompiles with any
  Vulgate-numbered 6-column TSV; only the ~12k cited verses are embedded.
- The hard liturgical logic stays in lectio (Go, oracle-validated); its
  clectio-gen emits the corpus-independent tables in gen/. The scripture text
  is LZSS-packed (lz.h) to fit; mktext/bin2h resolve+embed it at build time.
- Verified byte-identical to lectio's readings; day names match 157/157 over
  a 3-year sample. Default text: public-domain Latin Vulgate. ISC-licensed.
