9a80d059 (Migrate to new welshman) accidentally committed
link:../welshman/packages/* pnpm overrides into pnpm-workspace.yaml,
forcing resolution to a local welshman checkout that doesn't exist in
this environment. package.json already specifies the correct upstream
range (^0.9.0-pre2), so a fresh `pnpm install` produced dangling
node_modules/@welshman/* symlinks and broke `pnpm run dev`.
Drop the overrides (keep sharp) and regenerate pnpm-lock.yaml, which
now resolves upstream @welshman/*@0.9.0-pre5.
