Multiple tools conflict when installed together: .pnpm-workspace-state-v1.json collision

[elocke]

When enabling multiple steipete-tools plugins together (e.g. oracle and summarize) in a home-manager environment, the build fails with a pkgs.buildEnv conflict:

pkgs.buildEnv error: two given paths contain a conflicting subpath:                                                                                              
    `/nix/store/...-summarize-0.10.0/libexec/node_modules/.pnpm-workspace-state-v1.json' and                                                                       
    `/nix/store/...-oracle-0.8.5/libexec/node_modules/.pnpm-workspace-state-v1.json' 

Each tool's derivation outputs $out/libexec/node_modules/.pnpm-workspace-state-v1.json, which is a pnpm build artifact not needed at runtime. When nix-openclaw adds multiple tools to the home-manager path, buildEnv can't merge them.

Possible fixes:

• Remove .pnpm-workspace-state-v1.json from $out in the build (e.g. rm -f $out/libexec/node_modules/.pnpm-workspace state-v1.json in postInstall)

• Or namespace each tool's output under $out/libexec/<tool-name>/ to avoid collisions
