SourceLocation is attached to every AST node and cloned frequently
during map_context traversals, DeBruijn round-trips, and optimizer
passes. The module field was a String, making every clone a heap
allocation — despite all terms within a compilation unit sharing the
same module name.

Replace `module: String` with `module: Rc<str>` so clones are O(1)
reference count bumps. The Rc is created once per generate() /
generate_raw() call and shared via SourceLocation::with_rc().

Benchmark (104, largest acceptance test): 1.03x slower → 1.00x vs main.
