feat(constraint): two-category reader — prose to ConstraintProblem (R2 C5-C9)

generate/constraint_comprehension/reader.py: read_constraint_problem comprehends two-category constraint prose into a typed ConstraintProblem via five recognizers — C5 category-pair (from coefficient clauses; >2 -> too_many_categories), C6 coefficient (Each <cat> holds/has/costs/is-worth <N> <unit>; shared measured unit), C7 total-count (collective-unit sentence -> x+y=N; absent -> missing_total_count), C8 weighted-total (measured-unit sentence -> ax+by=T; absent -> missing_weighted_total), C9 query-target (How many <cat> -> the asked unknown). Refuses, never mis-assembles.

Reconciles the sketch's 'no equal coefficients' note: equal coefficients are a SOLVER refusal (indistinguishable_weights), not a reader one — the reader reads r2-010 setup_correct and the solver refuses it. run_reader lane + 'reader' CLI subcommand. R2 reader: setup_correct 10 / setup_wrong 0 / refused_correct 3; R1 7/0/3 and 15-case 15/0/0 unchanged. Off-serving. 8 reader tests incl. full read->solve->verify chain + meaningful-fail guards.

feat(constraint): R2 setup oracle + gold + ADR-0211 — the ruler (R2 C2)

evals/constraint_oracle: span-free canonical setup signature (unknowns/facts/constraints/query; terms merged+sorted, lhs constant folded into rhs), a 13-fixture gold (7 solved / 3 solver_refuses / 3 reader_refuses) with a closed expect+refusal taxonomy, and a gold-validation runner. No reader yet — this proves the ruler is coherent (13/13 valid), not capability.

ADR-0211 ratifies the R2 finite-integer two-category constraint compiler: the IR, the canonical signature, the closed taxonomy, the four wrong=0 gates (setup oracle / reader refusal / exact solver / answer-choice contradiction flag), off-serving disjointness, and the C1-C9 ladder. Cross-refs ADR-0207/0175/0083/0055-0057; reuses the R1 setup_oracle pattern. Off-serving (no generate.derivation / reliability_gate). 13 oracle tests incl. per-branch meaningful-fail.
