Config commands

These commands edit the config for a workbench you already created. They only change the yml (and seed any needed values into the env); the change takes effect on the next apply. Each kind of component has an add- command and a matching remove-.

Commands	What they do
add-language / remove-language	Add or remove a language toolchain (Node, Python, Go, …).
add-service / remove-service	Add or remove a backing service (Postgres, MySQL, Redis, or any image).
add-feature / remove-feature	Add or remove a devcontainer feature (AI agents, CLIs, SDKs).
add-mcp-server / remove-mcp-server	Give the agents an MCP server to reach, or take it away.
add-repo / remove-repo	Add or remove a git repo cloned into the workbench.
add-port / remove-port	Expose or stop exposing a port through the proxy.
add-apt-packages / remove-apt-packages	Add or remove Debian/Ubuntu apt packages.
add-from-url / remove-from-url	Add or remove an install script URL that runs on every rebuild.
