chore: add live reload support to docker

[techfg]

Live reload was added in #4586, however it does not currently support running in docker.

Running in docker presents a couple of nuances, primarily that the platform module is built as part of the image and that all local files are copied to the image rather than referenced from the host file system.

In order to support live reload, there are a couple of options:

1. Use docker watch command
2. Change the approach to image creation and resulting artifact to utilize the host file system instead of copying the files to the image itself

Pros/cons to both approaches.
