feature: example using path dependencies

[tibbe]

Even after days of trying I can't manage to create a Docker image with a multi-stage build that works for packages that use path dependencies. Here's an example package setup from a monorepo:

monorepo
├── service-a
├── service-b
├── library-a
└── library-b

Dependencies are as follows:

• service-a -> library-a and library-b
• library-a -> library-b
• service-b -> library-b

All dependencies use path dependencies e.g.

[project]
name = "service-a"
dependencies = [
    "library-a",
    "library-b",
]

[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

[tool.uv.sources]
library-a = { path = "../library-a", editable = true }
library-b = { path = "../library-b", editable = true }

Any suggestions would be much appreciated.
