feat: update dockerfile to support headless browsing and run better in a container

[samsheff]

Features

• An updated Dockerfile that supports headless browsing and a fully working environment

Feature Docs
To Build the docker image:
docker build -t manus .

To run it:
docker run -v ${PWD}:/app/OpenManus/workspace -it manus

The -v flag makes it so the workspace files can be retrieved after the task is complete. It is not required for use if its not needed in your use case. Also, by default it runs main.py, but this can be overridden using docker cli flags too (for running bash or the other scripts).

Influence
Dockerfile is the only file updated. It just adds support for browsing and fixes other issues using manus in a container. It also lets OpenManus run easily on windows.

Result

Other
Nothing else, unless there are questions.

Hey guys, just wanted to bump this. I know you have a lot of PR's open but figured this might be a quick one to review!

it may be worth decreasing the number of layers grouping the commands like:

RUN apt-get update && apt-get install -y && pip install playwright && playwright install --with-deps chromium

and also running it with alpine might optimize memory consumption.

Great PR btw, just few notes
