Include ref-macros.d.ts in npm dist files

Editor assessment

Correctly typed and helpful. Shipping `ref-macros.d.ts` is a packaging omission with type-level consequences, and while one could argue for `build`, `fix(types)` communicates the user impact, missing declarations breaking compilation for macro users, which is the more informative signal for changelog readers. The subject 'include ref-macros.d.ts in npm dist files' names the exact file and destination, is imperative, and fits all length guidance. The `fix #4433` footer links the report properly. The body stops at the reference; a line noting which release regressed the file would help, but the failure mode is self-evident from the subject. No structural issues: blank-line separation, valid footer token, no trailing period. A clean patch message.
