When pnpm is configured with shared-workspace-lockfile=false, each workspace gets its own pnpm-lock.yaml instead of a single root lockfile. turbo prune previously failed with 'no workspace found in lockfile' because it only looked for a root-level lockfile. This change reads shared-workspace-lockfile from .npmrc, discovers and merges per-workspace lockfiles into a unified lockfile for graph resolution, and ensures the pruned output uses a shared lockfile by rewriting .npmrc and cleaning up stale per-workspace lockfiles. Closes #3541

Summary
turbo prunefailing with "no workspace found in lockfile" when pnpm is configured withshared-workspace-lockfile=false([turborepo] prune doesn't support per workspace lockfiles #3541)pnpm-per-workspace-lockfile) that reproduces the scenarioProblem
When pnpm's
.npmrchasshared-workspace-lockfile=false, each workspace gets its ownpnpm-lock.yamlinstead of a single root-level lockfile. Turbo only looked for a root lockfile, so it either couldn't find it or found one that only contained the root's importers.Approach
.npmrcparsing —NpmRcnow readsshared-workspace-lockfilePnpmLockfile::merge_per_workspace_lockfiles()takes per-workspace lockfiles, re-keys their"."importers to the workspace's relative path (e.g.apps/web), and merges all packages/snapshots into a unified lockfilePackageManager::read_lockfile()checks.npmrcfor pnpm, and when per-workspace lockfiles are detected, discovers workspace dirs via globs and merges their lockfiles.npmrcis rewritten toshared-workspace-lockfile=trueTesting
To verify manually, build turbo and run against the new fixture:
Rust unit tests cover
.npmrcparsing and the lockfile merge logic.
