How to make TypeScript not emit `/// <reference path="…" />` directives for ambient declaration files?

Question

Background

I'm writing a package using Lit. To prevent accidental interpolation of nonsense values in templates, I have created src/lit.d.ts based on this answer:

declare module "lit" {
  import { html as htmlFromLit } from "lit/index";

  export * from "lit/index";

  export const html: (strings: TemplateStringsArray, ...values: Array<string | number /* etc */>) => ReturnType<typeof htmlFromLit>;
}

This way, I can write my code as usual and still get more type safety than Lit itself provides:

import { html } from "lit"; // ← standard, idiomatic import

export const h = html`<p>${null}</p>`;
//                         ~~~~ Argument of type 'null' is not assignable to parameter of type 'string | number'.

Problem

Consumers of my package get this compilation error:

node_modules/my-package/dist/index.d.ts:1:22 - error TS6053: File '/…/consuming-project/node_modules/my-package/src/lit.d.ts' not found.

1 /// <reference path="../src/lit.d.ts" />
                       ~~~~~~~~~~~~~~~

Content of /…/consuming-project/node_modules/my-package/dist/index.d.ts:

/// <reference path="../src/lit.d.ts" />
export declare const h: import("lit-html").TemplateResult<1>;

My observations/notes:

• lit.d.ts is indeed not among the emitted files in dist/, but even if it were, the reference would not point to it, because the src directory isn't included in the published npm package.

• There are no reference directives in the source code of my package; TypeScript injects them whenever it compiles a module that imports "lit".

• Even if I could make TypeScript include lit.d.ts among the emitted files, I don't think I want to, because its purpose is only to aid the development of my-package.

• If I manually remove the triple-slash directives in the emitted files before running npm pack, the consuming project compiles just fine.

• The problem is still present in TypeScript 4.9.5 and 5.0.4.

How can I make TypeScript not emit these directives, or otherwise solve this problem?
