We need additional documentation changes for the new devcontainer integration which is planned for GA in Summer 2025.

Namely:

• how to run devcontainers with pre-builds
• establishment of the "sub-agent" terminology for the improved agent injection (this terminology might potentially be also used in other areas of Coder, but for now the devcontainer integration is the first area where such terminology is required)
• optimization for devcontainer workspaces (e.g. volume cache)

In all of the above cases the dev team in persons of Danielle and Mathias are the best source of truth.
