Announcing rules_d: Bazel rules for the D programming language with bzlmod support

[Dragos Carp]

Hi everyone,

I’m happy to announce the availability of 
**[rules_d](https://registry.bazel.build/modules/rules_d)** — the 
Bazel ruleset for the D programming language, now with [Bazel 
module](https://bazel.build/external/module) (Bzlmod) support.

The goal of this project is to make D a first-class citizen in 
the Bazel ecosystem, so that you can build, test, and package D 
code alongside C++, Rust, Go, or any other languages supported by 
Bazel, all within the same build graph.

## Current Features
- `d_binary` and `d_library` rules for compiling D source files
- `d_test` rule for unit testing
- Support for multiple D compilers (DMD, LDC)
- Dependency handling and incremental builds via Bazel
- Interop with C/C++: `d_binary`, `d_library` and `d_test` 
targets can depend on `cc_library` targets
- Distributed via **Bzlmod** for straightforward integration:

```starlark
bazel_dep(name = "rules_d", version = "0.1.3")
```

## Get Involved
The project has been freshly reimplemented for bzlmod, so 
feedback and contributions are very welcome.

- GitHub: 
[https://github.com/bazel-contrib/rules_d](https://github.com/bazel-contrib/rules_d)
- Issues/feature requests: please open tickets
- Contributions: PRs are highly encouraged

I’m also looking for a co-maintainer. If you’re interested in 
Bazel, D, and polyglot build systems, please reach out!

If you’re already using Bazel or curious about experimenting with 
D in larger polyglot codebases, give it a try and let me know how 
it works for you.

Looking forward to your feedback!
