## Title

    [Goose] Extension blocked: 'Blocked malicious package: <pkg>@<ver> (npm). OSV MAL advisories: MAL-...' when launching npx/uvx extensions

## Body

    Cause (Documented platform behavior): Goose checks npm/PyPI packages of local extensions against OSV; if the service is unavailable, install proceeds.
    
    Fix status: documented_behavior
    
    Limitations:
    - Check silently skipped when OSV unreachable
    
    Other error fragments:
    - OSV MAL advisories:
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/aaif-goose/goose/main/documentation/docs/troubleshooting/known-issues.md (official_docs, unknown, documented_behavior): 'Malicious Package Detected' section documents the message and that the OSV check applies only to local npx/uvx extensions and fails open.
    
    Search phrasings: goose blocked malicious package OSV; mcp extension blocked malware advisory
    
    Evidence basis (self-declared by the contributing chat client): public_source.
