canary: prove a #16-shaped PR cannot merge (DO NOT MERGE)

[jeremylongshore]

What

Deliberately modifies crates/buzz-relay/src/main.rs (upstream-owned) to prove the new fork-contract required check goes red and blocks merging — the acceptance criterion in 000-docs/007-AA-AUDR-fork-contract-breach-2026-08-03.md §6.

Why one-line

A control you haven't watched fail isn't a control.

This PR will be closed unmerged once the red check is recorded. Refs #20.
