Specify compression method (zstd) when building (during up command) from compose file

Hi, I wanted to ask if there's a way to override the compression method when building a dev container image using `devcontainer up` and NOT `devcontainer build`.
I checked the spec but it's not supporting this under the `build` property. But maybe I missed something.
I saw this is supported in the build command. But the build command in turn does not support `--override-config` which im using.

Also, when I try to use --output during build command I get: `--output not supported`

Thank you!

Start by comparing how the `devcontainer up` and `devcontainer build` commands handle build options, especially compression, `--override-config`, and `--output`. Read the specification's `build` property and trace the existing command behavior; done means the requested option is supported consistently or its limitation is clearly documented.
