The previous multi-stage `deps` → `builder` split copied only the root
/app/node_modules from the deps stage, but pnpm workspaces also create
per-package node_modules directories (e.g. apps/web/node_modules) that
contain the .bin symlinks for `next`, `tsup`, etc. Without those, the
builder stage failed with `sh: tsup: not found` and `sh: next: not found`.
Collapse `deps` and `builder` into a single stage so the per-package
node_modules survive intact. pnpm's content-addressable store keeps
re-installs nearly free on cache hits, and Docker layer caching still
short-circuits the install step when only source files change.
For collab and mcp runner stages, also copy the per-app node_modules
so runtime dependency resolution works.

Coolify invokes `docker compose` with --project-directory set to the
repository root, not this file's directory. Previous `context: ..` was
resolving to /artifacts (one level above the repo) and failing with
`resolve : lstat /artifacts/docker: no such file or directory`.
Switch all three services (web, collab, mcp) to `context: .` so the
build context is the repo root and `dockerfile: docker/Dockerfile.X`
resolves correctly.
