Pull Request Overview

This PR updates the Rust CI workflow to unpin the nightly compiler version. Previously, the nightly version was pinned to nightly-2025-08-11 due to a compiler bug (rust-lang/rust#145288). The change removes this pinning and reverts to using the latest nightly version in the build matrix.

• Removed the pinned nightly-2025-08-11 version and replaced it with nightly
• Removed comments explaining the temporary pinning due to the compiler bug

Comments suppressed due to low confidence (5)
