chore(deps): bump pnpm 11.1.2 to 11.1.3

Cascade from socket-registry pnpm bump. Local dev was
already on 11.1.3; pinning packageManager here brings
the project's declared version in line with the installed
binary and unblocks CI runs that were failing with
packageManager version mismatch.

Pre-commit bypassed (SOCKET_API_KEY 401, user-authorized
via 'Allow lint bypass').
