Introduces internal/requestid package with shared context key to avoid circular imports between server and middleware packages. Server's RequestID middleware now uses the shared key. Client middleware picks up the ID from context and sets X-Request-Id on outgoing requests. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
