Fixes #18556 by using RUSTC_WRAPPER instead of setting RUSTFLAGS directly. This allows Homebrew's optimization flags to coexist with .cargo/config.toml settings, preventing build failures when projects have their own Rust configuration. - Add rustc_wrapper shim that clears RUSTFLAGS and prepends HOMEBREW_RUSTFLAGS - Update both std and super environments to use RUSTC_WRAPPER - Store Homebrew's rustflags in HOMEBREW_RUSTFLAGS instead of RUSTFLAGS 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> Co-authored-by: Carlo Cabrera <github@carlo.cab>
