PR Summary

Low Risk
Routine Renovate toolchain pin with no application logic changes; CI may surface new nightly compiler warnings only.

Overview
Bumps the repo Rust toolchain from nightly-2026-06-08 to nightly-2026-06-15 in rust-toolchain.toml.

Documentation badges in error-stack (crate README, macros README, and lib.rs crate docs) are updated to show 1.83.0/nightly-2026-06-15 so they match the pinned channel.
