[Feature]: LSP Support In Edit Tools

[ezynda3]

What feature would you like?

AI Coding tools like opencode integrate LSP tightly with their editing tools which gives LLMs additional context when editing files. See: https://github.com/sst/opencode/blob/dev/packages/opencode/src/tool/edit.ts

Basically any time an edit tool is called, it should also check for diagnostic messages from any configured LSPs to return as part of the normal edit tool response. This way the LLM can see if it made some mistake and immediately fix it.

Why would this be useful?

This leads to less turns/edits and less time for the LLM spinning its wheels to understand random issues.

i'd love this and have taken a couple stabs at it. the idea of including the diagnostics as part of the edit/write/etc responses is cool, too, my initial attempts at impl always only had a separate diagnostics tool.
