File tools performance fixed ✅

A few of you told us that some tools call like view and edit were sometimes taking a few seconds to complete, making your sessions slow to proceed. Well, that happened because Crush notifies LSP servers about the files you're viewing or touching, and waits for a response. Some LSPs are slow, and it things took some time to happen.

In this release we not only made a good number of fixes to file tools + LSPs, but we also added a 300ms timeout so if something got stuck Crush will proceed anyway.

The find_references also got fixes. It allows the model to query for your LSPs to find refences for a given type/function/etc.

Special thanks to our favorite contributors @huaiyuWangh and @taigrr to helping and testing these improvements! ✨

Enjoy your weekend!
