Reproduction steps

Steps to Reproduce

1. pnpm i --frozen-lockfile

Describe the Bug

When attempting to install from a lockfile that points to a file:./package.tgz, the resolver appears to attempt to find that package on the registry rather than using the local file tarball as instructed. This functionality worked in pnpm@10, but has regressed in pnpm@11

Expected Behavior

• The installation should succeed without any errors.

Actual

• The installation fails with the following error:

ERR_PNPM_FETCH_404  GET https://registry.npmjs.org/test-package/-/test-package-1.0.0.tgz: Not Found - 404

Note: This error is not reproducible using the pnpm@10 branch https://github.com/kaidjohnson/pnpm11-bug/tree/pnpm%4010
