Moves chunk sidecar env and chunk sidecar build into a new top-level chunk env detect command with --format json|dockerfile. Detection is no longer a sidecar-specific concern, and the docker build step is removed from the CLI — callers run docker themselves. Acceptance test renamed from sidecars_build_e2e_test.go to env_detect_e2e_test.go; e2eRunBuild split into e2eRenderDockerfile and e2eDockerBuild to make the two-step flow explicit.

chunk env init now writes Dockerfile.test by default; --format json opts into the JSON spec. This better reflects the intended use as a project initialization step (detect stack, produce Dockerfile, cache to config) rather than a pure inspection command.

we're dropping chunk's tag validation here now that docker build is run by the user instead of by chunk. it'll still reject a bad tag, with its own error - but wasn't sure if it was intentional - just a ux thing i guess!

Yeah, this was intentional - under the assumption we may as well just have the user run docker build themselves

err i might be missing this but i can not find the detect subcommand. naming mismatch?

Good catch, this was a naming mismatch - fixed now!

Summary
The thinking here: if we want to use dockerfiles as the basis for spinning up lots of sidecars, having a command to generate the dockerfile directly, rather than as a side effect of
chunk sidecar env | chunk sidecar build --dir, may be a smoother experience.chunk env initas a new top-level command that detects a repository's tech stack and writesDockerfile.testto--dir(default), or prints the environment spec as JSON (--format json). The detected spec is saved to.chunk/config.jsonfor reuse bychunk sidecar setup.validate.gothat referencedchunk sidecar env build(a command that never existed); it now correctly suggestschunk sidecar sync.Before / after
