Please tell us more about your question or problem

When using pnpm named catalogs (not the default catalog) in pnpm-workspace.yaml, Renovate updates the catalog version entry but does not regenerate pnpm-lock.yaml.

This causes pnpm install --frozen-lockfile to fail with:

ERR_PNPM_LOCKFILE_CONFIG_MISMATCH Cannot proceed with the frozen installation.
The current "catalogs" configuration doesn't match the value found in the lockfile

The PR diff only contains changes to pnpm-workspace.yaml and pnpm-lock.yaml is completely absent.

Describe what you expected to happen instead

Renovate should regenerate pnpm-lock.yaml when it modifies named catalog entries in pnpm-workspace.yaml, just as it does for regular package.json dependency updates.

Minimal reproduction

https://github.com/xballoy/renovate-pnpm-named-catalog-repro

The setup:

• pnpm-workspace.yaml with a named catalog (backend) containing typescript: 5.0.2
• package.json referencing "typescript": "catalog:backend"
• pnpm-lock.yaml generated and committed

Renovate PR: xballoy/renovate-pnpm-named-catalog-repro#4

• Updates pnpm-workspace.yaml (typescript: 5.0.2 → 5.9.3)
• Does not update pnpm-lock.yaml
