💥 Make typer-slim a shallow wrapper around typer, always requiring rich and shellingham

[svlandeg]

From a recent survey we've run on Typer, we've learned that less than 5% of users specifically use typer-slim. We had originally introduced this package to provide users the option to not install shellingham & rich. However, even with these two packages, the typer library is still pretty small (25Mb) and the code base is more complex by having to cater for custom logic whether or not Rich is present or not. Additionally, we've run into issues (#1503) with publishing typer and typer-slim from the same codebase, so we can't keep the current situation. All of this has resulted in the conclusion to drop support for typer-slim. It will just be a shallow wrapper around typer.

We are aware that some users do not prefer some of the Rich formatting, and we'll look into options of customizing this further in the future. For now, there is always the option of setting Typer(rich_markup_mode=None) for each app, or setting a global environment variable TYPER_USE_RICH to False to disable any Rich formatting.

I've built the wheel locally (with TIANGOLO_BUILD_PACKAGE="typer-slim") and installed it in a clean venv, and got:

$ pip list
Package           Version
----------------- -------
click             8.3.1
colorama          0.4.6
markdown-it-py    4.0.0
mdurl             0.1.2
pip               25.2
Pygments          2.19.2
rich              14.3.2
shellingham       1.5.4
typer             0.21.1
typer-slim        0.21.1
typing_extensions 4.15.0

Great, thank you! 🙌

The PDM hook and config logic is a bit cumbersome, strange, and hard to test. 😅

I added some tweaks for that:

• Tweak the PDM hook script and config in pyproject.toml to make typer-slim do not include any code and only depend on typer (it was including the typer code in typer-slim)
• Add a custom README for typer-slim to tell users to not use it
• Make typer-slim and typer-cli depend on typer>={version} instead of typer=={version}, so that we can remove all this stuff later at some point
• Update the logic in the PDM hook and configs so that by default, even if we removed all that extra logic, it would build regular typer, without needing any extra custom config
• Update the test-redistribute in CI to only test for typer

This will be available in Typer 0.22.0 in the next few hours. 🚀
