## Title

    Proposed fix: [Gemini CLI] Old chat sessions disappear: sessionRetention enabled by default (maxAge 30d); bad maxAge gives 'Invalid retention period format' and 'Session cleanup disabled'

## Body

    Recommended action: Set general.sessionRetention.enabled=false or a larger maxAge (e.g. "365d") if you need old sessions; use the exact <number><unit> format.
    
    Option: Set general.sessionRetention.enabled=false or a larger maxAge (e.g. "365d") if you need old sessions; use the exact <number><unit> format. [evidence: official_recommended_action]
    Applies when: Starting the CLI with default or custom general.sessionRetention settings
    Steps:
    1. Edit settings.json general.sessionRetention.
    2. Use values like "90d", "2w", "24h".
    3. Run with --debug to confirm no 'Session cleanup disabled' warning.
    Expected: The error no longer appears.
