Fastify v5 uses diagnostics_channel.tracingChannel() which only exists in Node.js >= 20. Without an engines constraint, users on older Node versions hit a cryptic TypeError at startup. This gives a clear error at install time instead. Fixes: TE-12603 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
