Reproduction steps

corepack pnpm@11.2.0 install --lockfile-only --ignore-scripts
corepack pnpm@11.2.0 install --frozen-lockfile --ignore-scripts

Describe the Bug

pnpm@11.2.0 with the pacquet install engine fails to parse a lockfile when an injected workspace package snapshot depends on another workspace package via a link: path.

The install fails while pacquet parses the lockfile:

Failed to parse the version part: Failed to parse version.
  --> <input>:37:10
   |
35 |   b@file:packages/b:
36 |     dependencies:
37 |       c: link:packages/c
   |          ^ Failed to parse the version part: Failed to parse version.

Expected Behavior

The frozen install succeeds, matching the non-pacquet pnpm install behavior.
