There were too many ways to configure the agentcontainers API resulting
in inconsistent behavior or features not being enabled. This refactor
introduces a control flag for enabling or disabling the containers API.
When disabled, all implementations are no-op and explicit endpoint
behaviors are defined. When enabled, concrete implementations are used
by default but can be overridden by passing options.
This change allows listing both predefined and runtime-detected
devcontainers, as well as showing whether or not the devcontainer is
running and which container represents it.
Fixescoder/internal#478
This refactor improves separation of API and containers with minimal
changes to logic.
Highlights:
- Routes are now defined in `agentcontainers` package
- Handler renamed to API
- API lazy init was moved into NewAPI
- Tests that don't need to be internal were made external
