## Title

    Proposed fix: [Playwright MCP] Config conflicts: 'Browser userDataDir is not supported in isolated mode.' / 'Cannot use --mobile together with --device' / 'Device emulation is not supported with cdpEn

## Body

    Recommended action: Drop one of the conflicting options (check PLAYWRIGHT_MCP_* env vars too).
    
    Option: Drop one of the conflicting options (check PLAYWRIGHT_MCP_* env vars too). [evidence: official_recommended_action]
    Applies when: Combining --isolated with --user-data-dir, --mobile with --device, or --device with --cdp-endpoint
    Steps:
    1. Remove --user-data-dir when using --isolated (use --storage-state for initial state)
    2. Pick --mobile or --device
    3. Don't use device emulation when attaching via --cdp-endpoint
    Expected: The error no longer appears.
