RULE 0.2 Rust First

Rust is the default. Other languages need an explicit architectural reason BEFORE writing code.

Performance + single-binary + no runtime + no version skew.

Exceptions: ML training >10M params, language-locked existing project, platform-native UI, browser/DOM, <50-line one-shot. State the exception number.
