Phase 3: Intelligence — 613 mitzvot, 13 middot, Tzara'at diagnostic

Encode all 613 mitzvot from Rambam's Sefer HaMitzvot (248 positive,
365 prohibitions). Build the 13 Middot of Rabbi Yishmael as Prolog
inference predicates for hermeneutical reasoning. Implement Tzara'at
multi-stage input validation following Vayikra 13-14. Enhance kushya
generation with kal vachomer and shnei ketuvim challenge strategies.

Architecture §4 Steps 14-15, 19-20.

New files:
  middot/   — 8 files (master + 7 rule modules)
  diagnostic/ — 4 files (tzaraat, inspection, quarantine, diagnosis)

Modified:
  mitzvot.pl     — 52 → 613 mitzvot
  relationships.pl — expanded tensions, complements, action domains
  challenge.pl   — middot-based kushya (kal vachomer, shnei ketuvim)

Tests: 293 total (184 Prolog, 76 Elixir, 33 Haskell), 0 failures.
