Describe the Bug

node_modules contains workerd + vitest + esbuild + wrangler + etc, which quick amounts to 200MB.
When doing npx wrangler deploy, the directory is compressed (tar) and sent to the Docker engine.
This can be controlled with .dockerignore, or better yet by moving the Dockerfile to a subdirectory.

I think the Go server template would benefit from either:

• having Dockerfile in container_src
• adding .node_modules / .git to .dockerignore.

These only affect build speed (and so, deployments). Discoverability / explainability of what's running in Isolates vs Container may benefit/suffer from this.

In my small test env, cached builds take ~8s, drops down to ~1.6s with node_modules/ in .dockerignore.

Please provide any relevant error logs
