Iter 4a: ail check --json mit strukturierten Diagnostics
Neue Top-Level-API check_module(&Module) -> Vec<Diagnostic> in ailang-check, plus stabile Codes (unbound-var, type-mismatch, arity-mismatch, non-exhaustive-match, unknown-ctor-in-pattern, duplicate-def, …). CLI bekommt --json-Flag für maschinenlesbares Output, Exit 1 bei Errors. Text-Modus unverändert. E2E-Test check_json_unbound_var sichert das Format ab.
