fix: Only compute unstable paths on nightly toolchains for IDE features

Commit: 9db0550
Release: 2025-08-11 (v0.3.2577)
An Update on the Next Trait Solver
We are very close to switching from chalk to the next trait solver, which will be shared with rustc.
chalk is de-facto unmaintained, and sharing the code with the compiler will greatly improve trait solving accuracy and fix long-standing issues in rust-analyzer.
This will also let us enable more on-the-fly diagnostics (currently marked as experimental), and even significantly improve performance.
However, in order to avoid regressions, we will suspend the weekly releases until the new solver is stabilized.
In the meanwhile, please test the pre-release versions (nightlies) and report any issues or improvements you notice, either on GitHub Issues, GitHub Discussions, or Zulip.
