bundled marketplace JSON should serialize

Error message

bundled marketplace JSON should serialize

What it means

Expect/invariant assertion when generating the bundled marketplace JSON: serde_json failed to serialize a struct the code just built from known-good literals, which should be impossible. Firing indicates corrupted constant data or resource exhaustion while building the 'OpenAI Bundled' manifest.

Solutions

1. Restart the operation; this is an invariant violation, not user-fixable
2. Report a bug with the plugin list being serialized if it reproduces
3. Check available memory if failures are intermittent
