Shay f66f2ee47f feat(comprehend): propositional-logic comprehension (4th domain, flagship oracle)
Adds comprehension_propositional — the comprehension organ now reads the classic
propositional ARGUMENT FORMS end-to-end into the flagship deductive_logic ROBDD
oracle (the most robustly independent gold in the repo). The neutral MeaningGraph
now feeds FOUR independent oracles (set-membership, syllogism-validity,
total-ordering, propositional-entailment) from one interlingua — the Option-B
interlingua thesis validated.

reader.py: propositional templates (atoms are chunked NP ids; fits the existing
entities + n-ary relations + negation model — NO interlingua change, propositional
is not arithmetic-quantities):
  - "if <P> then <Q>"        -> implies(P, Q)
  - "not <P>"                -> asserted(P, negated=True)
  - "<P> or <Q>"             -> or(P, Q)
  - "<P>" (single token)     -> asserted(P)   (bare-atom, single-token only to
                                                keep the parse-or-refuse floor)
  - "therefore <prop>"       -> query of the same predicate
Relations now carry a negated flag end-to-end (asserted negation).

projectors.py: to_deductive_logic serializes propositional relations/query into
formula strings (keyword operators the oracle tokenizer accepts); returns None
(refusal) unless the comprehension is purely propositional, so categorical/ordering
comprehensions never leak into the entailment oracle.

evals: new evals/propositional_logic/v1 (12 cases — modus ponens/tollens,
hypothetical & disjunctive syllogism, the affirming-consequent / denying-antecedent
fallacies which the oracle marks "unknown"; gold = oracle verdict) + gold-only
runner + evals/comprehension/propositional_runner.py. Oracle "refused" (formula
unevaluable) is treated as a decline, never a wrong.

Scores: comprehension_propositional 12/12 wrong=0 (full coverage); no regression on
the 3 existing lanes (8/8, 7/8, 7/8). Capability index breadth 6->7, score
0.917231 -> 0.928622, wrong_total 0, digest 51df7bba…

Tests: reader propositional templates; to_deductive_logic projector tests;
end-to-end full-coverage wrong=0; propositional generative round-trip added to the
wrong=0 property suite (verified to BITE under a reversed-implies mutation);
capability breadth 6->7. 115 targeted + 87 smoke green. Lane SHAs 8/9 (sole miss =
public_demo env wall-clock flake; deductive_logic_v1 unchanged).
