## Title

    Proposed fix: [Anthropic Go SDK] 'no Anthropic credentials found. The SDK tried these sources in order:' and credentials file refused for unsafe permissions/symlink

## Body

    Recommended action: Set ANTHROPIC_API_KEY, or run `ant auth login`, or configure ANTHROPIC_FEDERATION_RULE_ID/ANTHROPIC_ORGANIZATION_ID/ANTHROPIC_IDENTITY_TOKEN_FILE; chmod 600 the credentials file and point ANTHROPIC_CREDENTIALS_PATH at the real (non-symlink) file.
    
    Option: Provide a credential and fix file perms [evidence: official_recommended_action]
    Steps:
    1. export ANTHROPIC_API_KEY=... or ant auth login
    2. chmod 600 <credentials file>
    3. for symlinked mounts: export ANTHROPIC_CREDENTIALS_PATH=<resolved path>
    Expected: Client authenticates
    
    Evidence basis (self-declared by the contributing chat client): untested.
