Describe the bug / provide steps to reproduce it

Related: #15692 #17937

Zed Version: 0.152.4
Architecture: x86_64
OS: Ubuntu 24.04

When I use inline assist on my file with 19k tokens, zed starts eating up all my ram and swap then my whole system crashes shortly afterwards.

File I was performing inline assist on(in hopes of improving reproducability)
https://github.com/flxzt/rnote/blob/main/crates/rnote-engine/src/pens/typewriter/penevents.rs
I was telling Zed AI in the inline assist feature after selecting the whole script to "remove occurrences of audio usage"

I can give an step to reproduce.

• open zed code with Zed
• ctrl-p select x11/window.rs file
• select all contents
• using inline assist with prompts "can you find bug"
• eat all ram, then unresponse.
