1.4.0

• Migrated DATA statements to the unified token, AST, and typed IR pipeline, including multiple groups, repetition factors, and arbitrarily nested implied DO loops.
• Added pre-emission semantic validation for initialization constants, types and kinds, element counts, array bounds, duplicate initialization, and resource limits.
• Corrected one-time initialization and SAVE lifetime semantics for scalars, arrays, characters, complex values, and EQUIVALENCE storage roots.
• Lowered portable scalar, whole-array, partial-array, and implied-DO initialization to efficient, readable C17 static initializers.
• Expanded strict C17, repeated-call, negative-diagnostic, and pinned Reference BLAS/LAPACK official numerical differential coverage.
