feat: Add Angular Adapter

[benjavicente]

🎯 Changes

This PR adds an Angular Adapter + examples for each main function exported.

There is not devtools package yet, since there is no createAngularPlugin in @tanstack/devtools-utils.

I had to dowgrade TS from 5.9 to 5.8 since it's the latest TS version Angular 19 supports. It supports angular 19 and up since 19 is the oldest with LTS.

A lot of the code was AI asisted, but I reviewed and refractored the adapter to match as closelly as the solid adapter.

Hi, I'm also following along with this PR. Consider merging main back in to resolve some larger conflicts.

The sequence was rewritten to a much more in-depth sequence-manager today with full parity with the hot-key manager.

[benjavicente]

Rebased the branch with the sequence-manager 🏃

For the input signal issue: I added a temporary approach in injectHotkeyRecorder to create the store (HotkeyRecorder) post initialization in a stable signal. We could swap that to a standardized solution when we land something in TanStack/store#284 (discussion) or TanStack/store#285 (alternative API PR).

I can see that a rebase was performed last week, but conflicts already exist again. I'm guessing that because the library is iterating quickly that non-react adapters are going to take some time to get merged in?

Edit: Should've done a bit more homework. looks like the README points out React/Preact/Solid are in but Angular et al. say they need contributors. But the only adapter listed in the Tanstack docs right now is React. Apologies!

@adamwendel the issue was that TS versions didn't match, I think we only need some reviews 😃

I upgraded to angular 21 to be consistent with our other tanstack packages, but kept the peer dep at >19
