feat(deployments): split project dependencies and code into separate layers

[myftija]

Deploy images previously shipped node_modules and the bundled task code in a single layer, so every deploy re-pushed and re-pulled the full dependency tree even when nothing in it changed. The generated Containerfile now copies /app/node_modules as its own layer and the app files separately. With unchanged dependencies the dependency layer is identical across deploys, so registries and workers already have it and only the code layer moves.

Walkthrough

Node and Bun Containerfiles now create separate dependency and application-code layers. The build stage retains node_modules, while a new code stage excludes it before the final image copies both sources separately. Tests cover layer separation and command ordering for both runtimes. A patch Changeset documents the image-layer update.
