feat: would like powercontext to launch and run in the background

Feature description

As the title suggests:

1. I hope powercontext can run as a background process; currently, keeping a terminal window open just to run a background process feels rather inelegant.

2. Have you considered deploying and running it via a Docker container? This would allow for deployment on any machine—including Windows—provided Docker Desktop is installed.

Problem and proposed solution

1. Currently, a running powercontext process requires a dedicated terminal window, which isn't exactly elegant; running it in the background would free up the terminal window completely.

2. Supporting Docker deployment would allow it to run on any machine—including Windows—provided Docker Desktop is installed.

Are you willing to contribute to this feature?

• Yes, I am willing to contribute code, docs, or design feedback.

Start by locating the powercontext launch entry point and any existing deployment configuration. Define how it should run without a dedicated terminal and how Docker should start it across supported machines. Done means both background execution and Docker deployment are documented and tested.
