Assistant: Option to Fix error in Chat with additional context

Feedback

In Positron, there is a Quick Fix and Fix with Assistant option on static errors in source code:

Some users find the inline fixes too aggressive to diff and edit the code, rather than let them provide a bit of context and then send the LLM off to attempt a fix.

I'd love for "Fix with Assistant" to have a counterpart "Fix in Chat". Sometimes the inline fix works and its great, but very often I find that I need to give the assistant more context before it'd be able to give me a reasonable answer and the "Fix with Assistant" gesture moves too quickly because it jumps straight into streaming an answer

The user is aware of the menu option to View in Chat

However:

Yes! But that’s only an option after I’ve started the fix with assistant streaming, usually by then PA is a bit off the rails and it can be hard to get it back on track. (My general LLM experience is that it’s better to get context right from the start than to try to correct the LLM into to the right answer)

Design

We should have an option to open an error in Chat where Assistant will ask for more information and then allow the user to dictate when to start "thinking" of a fix.

The issue names no files, tests, or entry points. Start by tracing the existing “Fix with Assistant” and “View in Chat” actions, then verify that an error can open Chat for context before streaming begins and that the user can explicitly start the fix.
