Imhotep-core: add predicate-specs.ts with 34 PredicateSpec entries as
the single source of truth for predicate metadata (name, arity,
aliases, requiredFacts, validOptions, diagnosticCode, relationCode,
decompose rules, category flags). Lookup helpers derive all
per-predicate information from the static table.
Extraction.ts (3 consumers converted):
- computeRequiredFacts: replace getRequiredFactsForPredicate (global
registry) with getPredicateRequiredFacts (static spec table).
Removes registerDefaultPredicates() dependency from fact planning.
- compileCanonicalClauseToFormula: replace 4 string-branch patterns
('between'/'separatedFrom'/'atLeast'/'aspectRatio'/'inStackingContext')
with spec-driven getPredicateDecomposition() and isUnaryPredicate().
Same behavior, zero string dispatch in predicate selection.
- mapFolDiagnostic: replace PREDICATE_TO_DIAGNOSTIC_CODE (13-entry
Record) with getPredicateDiagnosticCode() from spec table.
595 SDK + 57 hard E2E tests pass.
