docs(suggestion): adding a list of supported Nextjs cache functionalities

Hi all,

I'm currently working with the latest Next.js 15 canary release and have been testing some of the new experimental caching features like:

```
cacheTag();
cacheLife();
```
Alongside more stable APIs such as:
```
revalidateTag();
```
So far, some of the the experimental features appear to be working well which is great!

That said, I believe it would really help adoption within the Next.js community if there were clearer guidance or documentation indicating which caching APIs are supported, and to what extent. A simple compatibility matrix or stability indicator would make it easier for developers to use this package.

Keep up the great work, and thanks for continuing to push the platform forward!
