PR Summary

Low Risk
Routine patch nightly bump with no application logic changes; only CI/local compiler version and documentation badges.

Overview
Bumps the repo Rust toolchain from nightly-2026-07-06 to nightly-2026-07-13 in rust-toolchain.toml (components unchanged).

Updates the rust-version badge text in error-stack docs (libs/error-stack/README.md, libs/error-stack/src/lib.rs) and error-stack-macros (libs/error-stack/macros/README.md) so they match the new nightly pin.

Stale mise Rust toolchain lock

Medium Severity

rust-toolchain.toml now targets nightly-2026-07-13, but .config/mise/mise.lock still locks Rust at nightly-2026-07-06. With idiomatic_version_file_enable_tools = ["rust"] and lockfile = true, mise-managed installs (including mise install --locked in CI) can resolve or reject the wrong nightly relative to the updated toolchain file.

Footnotes

1. 80 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (602f13f) during the generation of this report, so 15de8ae was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
