Use nightly cargo + esp rustc (RUSTC override) + -Zbuild-std=core for Xtensa targets. This avoids the esp cargo's inability to parse modern crate manifests (edition 2024) while still using esp's LLVM with full Xtensa support. Pin proc-macro-crate to 3.2.0 to avoid transitive deps requiring rustc 1.85+. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
