## Title

    Proposed fix: [browser-use] Local launch: profile lock retries with a temp user_data_dir ('Browser launch failed (attempt n/N)'), then 'Failed to launch browser after N attempts' or 'Browser did not s

## Body

    Option: Close other Chrome instances using that profile or copy the profile to a dedicated directory; check the warnings to see whether a temp profile was used; fix container deps if the browser never starts. [evidence: official_recommended_action]
    Applies when: Launching a local browser with a persistent user_data_dir (e.g. your real Chrome profile) or in a slow container
    Steps:
    1. Quit Chrome or use a copy of the profile directory.
    2. Watch for 'Retrying with temporary user_data_dir' in debug logs.
    3. In containers install system deps / use headless.
    Expected: The error no longer appears.
