fix(lsp): cancel pending requests before refreshing

Browse Source 
Problem:
Diagnostics and inlay hints can be expensive to calculate, and we
shouldn't stack them as this can cause noticeable lag.

Solution:
Check for duplicate inflight requests and cancel them before issuing a new one.
This ensures that only the latest request is processed, improving
performance and preventing potential conflicts.
