twilio-client (Twilio Messaging end-to-end)

Motoko bindings for Twilio Messaging, generated from Twilio's two upstream OpenAPI specs (Messaging V1 + API v2010) merged into one client. Two concerns are kept distinct but both handled here:

• Configuration — Messaging Services, A2P 10DLC brand / campaign / number-assignment, toll-free verification, sender-pool settings, link shortening, domain certs. All on the v1 surface (MessagingV1*Api), hosted at messaging.twilio.com.
• Delivery — createMessage / fetchMessage / listMessage, MMS media, user-defined message events, owning + buying numbers. On the v2010 surface (Api20100401*Api), hosted at api.twilio.com.

The two hosts are routed per operation at codegen time — callers see one Config and one credential pair, not two.
