Language Server Panic (Exit Code 101) on startup (Django 5.0.14 project)

[Monshiy]

The Pyrefly language server crashes repeatedly immediately upon opening the editor (startup). After 5 attempts, the server stops restarting. The logs indicate a panic in pyrefly::alt::solve and pyrefly::alt::expr, likely due to a stack overflow or deep recursion during the initial analysis/type inference.

I am working on a Django 5.0.14 project. Given the stack trace, it seems the server struggles to resolve some bindings or types specific to the Django framework structure during the initial indexing.

Steps to Reproduce
Open the Antigravity editor.

Load a project using Django 5.0.14.

The server crashes immediately during the initialization/indexing phase.

This occurs consistently on the first open.
