Check a message's status

GET /v1/messages/:id

GET /v1/messages/:id with the msg_… returned by POST (a numeric id → 404). One status vocabulary: queued | sending | sent | delivered | read | failed | held. ⚠ Terminal: only read and failed. delivered is NOT terminal (delivered→read is valid) — if you stop polling at delivered you never see the read.
