[BUG] `npm install` missing exactly one file in exactly one dependency package

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

This is not just a request to bump a dependency for a CVE

• This is not solely a request to bump a dependency for a CVE

Current Behavior

• If I run npm install at the root of https://github.com/NousResearch/hermes-agent, the file dist/tabler-icons-react.d.ts must be present in node_modules/@tabler/icons-react, but is missing.
• The next step to build the desktop app, namely npm run build -w apps/desktop fails at tsc -b with errors due to missing type declaration.
• Build succeeds if I manually insert the file from the tarball I got from npm registry.

Expected Behavior

npm install and then npm run build -w apps/desktop succeeds.

Steps To Reproduce

1. On windows, git clone https://github.com/NousResearch/hermes-agent
2. npm install at the project root
3. Observe the contents in node_modules/@tabler/icons-react to see if the file dist/tabler-icons-react.d.ts is present
4. npm run build -w apps/desktop at the project root to see "type declarations missing" errors from tsc -b (more complete description and what I tried to fix it can be found in https://github.com/NousResearch/hermes-agent/issues/38146#issuecomment-4778032787)

Environment

• npm: 11.17.0
• Node.js: 24.15.0
• OS Name: Windows 11
• System Model Name: Dell OptiPlex 7000 (desktop)
• npm config:

cafile = "corporate certificate (redacted)"
registry = "corporate npm proxy (redacted)"
; no other configs set

The corporate proxy is not the cause, since the tarball downloaded from the proxy does contain the offending file, and it is present when I npm install @tabler/icons-react from a fresh project.

Reproduce la instalación del repositorio hermes-agent en Windows y, después, inspecciona node_modules/@tabler/icons-react en busca de dist/tabler-icons-react.d.ts. Ejecuta npm run build -w apps/desktop y compara el paquete instalado con el tarball de npm; se considera terminado cuando npm install incluye la declaración y la compilación de desktop se completa correctamente.
