Prevent checking if model exists on every autocompletion

[dhuertas]

Hi!

Thanks for coding this little wonder of extension. Kudos! I've been using it for a bit, and I have noticed that every autocompletion generates an extra request to the /api/tags endpoint in Ollama:

I suspect it comes from the call to ollamaCheckModel() in provideInlineCompletionItems():

In my view it should not be necessary to send a request to the /api/tags endpoint every time. I am aware the latency it introduces is orders of magnitude lower than the /api/generate cat, but still ... it's extra job for the extension that (in my view) does not need to do.

I'd suggest to go for a different strategy 🤔 Perhaps do the check once and save the list of available models to check locally. Then check again whenever the configuration changes, or every now and then.

Thanks!
