## Summary
The implicit namespace package rule currently fails to detect cases like
the following:
```text
foo/
├── __init__.py
└── bar/
└── baz/
└── __init__.py
```
The problem is that we detect a root at `foo`, and then an independent
root at `baz`. We _would_ detect that `bar` is an implicit namespace
package, but it doesn't contain any files! So we never check it, and
have no place to raise the diagnostic.
This PR adds detection for these kinds of nested packages, and augments
the `INP` rule to flag the `__init__.py` file above with a specialized
message. As a side effect, I've introduced a dedicated `PackageRoot`
struct which we can pass around in lieu of Yet Another `Path`.
For now, I'm only enabling this in preview (and the approach doesn't
affect any other rules). It's a bug fix, but it may end up expanding the
rule.
Closes https://github.com/astral-sh/ruff/issues/13519.

The Ruff Language Server
ruff server is a language server that powers Ruff's editor integrations.
The job of the language server is to listen for requests from the client (in this case, the code editor of your choice) and call into Ruff's linter and formatter crates to construct real-time diagnostics or formatted code, which is then sent back to the client. It also tracks configuration files in your editor's workspace, and will refresh its in-memory configuration whenever those files are modified.
Refer to the documentation for more information on how to set up the language server with your editor and configure it to your liking.
