expose ngrx documentation via llms.txt file on ngrx.io site

[markgoho]

Which @ngrx/* package(s) are relevant/related to the feature request?

store

Information

essentially, we'd like an https://ngrx.io/llms.txt and https://ngrx.io/llms-full.txt file to point LLMs at to provide better context to Copilot, Cursor, etc.

example: https://angular.dev/llms.txt

Describe any alternatives/workarounds you're currently using

language models have some awareness of NgRx in their base training, but lack the nuance provided in the documentation

I would be willing to submit a PR to fix this issue
