feat: dynamically fetch and embed AI models list

[abhinavgautam01]

fixes #42....

Description

This PR addresses the need to detect a wide variety of AI models (like the extensive lists available in Cursor) without requiring a manual patchwork PR for every new model combination released...

It introduces a go generate script that fetches a comprehensive list of models dynamically from the OpenRouter API. The script cleans the data, filters out noise, and generates a native models.go file containing all recognized AI models to be used by the tool mention detector..

Changes Made

• Added detection/toolmention/generate.go to fetch the OpenRouter models API and generate a sorted Go array of model names.
• Added a //go:generate go run generate.go directive in detection/toolmention/toolmention.go.
• Updated the init() function to append the dynamically generated models to the base tools array prior to regex compilation.

Testing

• Ran go generate ./... locally which successfully created models.go populated with hundreds of current models.
• Verified that all unit tests in go test ./... pass successfully.
