1.3.0

• Added a dedicated, bounded conditional preprocessor with dynamic nesting, complete integer expression evaluation, and recursive object-macro expansion.
• Added #include, Fortran INCLUDE, #line, and numeric line markers while keeping the core library file-system independent through callbacks.
• Added API preprocessor definitions and CLI -D, -U, and -I options with explicit project and source-local macro scopes.
• Unified source mapping across preprocessing, source normalization, and tokens so structured diagnostics report both macro expansion and definition locations.
• Added request-level budgets and negative tests for preprocessed bytes, macro count and depth, and include count and depth.
• Expanded dedicated preprocessor, CLI include, cross-compiler, sanitizer, and full pinned Reference LAPACK regression coverage.
• Fixed the preprocessor test's SIZE_MAX declaration portability under strict LLVM/Linux builds.
