0.1.1

• Fixed: a duplicate opt-in confirmation message that loses the claim no longer deletes the pending retry of the
  one that is sending it (or gave it back to retry after a refusal): the pending row ends only when the number's
  confirmation is complete. Before, that confirmation could silently never be sent.

0.1.0

First release. Requires Magento 2.4.4 or later and commercekings/module-notification.

• Rate limits and server errors: HTTP 429, or 503 with Retry-After, is Notification's
  TemporaryFailureException (nothing sent, try again after the wait); any other 5xx counts as maybe sent
  (MessageSentException, never sent twice) - the timeout/5xx rule in docs/provider-api.md.
• Providers: Twilio SMS (twilio_sms) and WhatsApp (twilio_whatsapp) for Notification's channels, with the
  provider selectors under Channels and providers; credentials per website (the auth token encrypted); SMS from a Messaging
  Service or a number, WhatsApp from its number; every message asks for the status webhook.
• WhatsApp templates: Content SIDs per notification type and locale, with the notification's variables in order.
• Reply webhook (/cktwilio/webhook/inbound): STOP words and WhatsApp's "Stop promotions" stop the number until
  START (StopListInterface::REASON_REPLY); Twilio's signature checked against the configured public URL.
• Status webhook (/cktwilio/webhook/status): undeliverable numbers are suppressed with their consents kept
  (REASON_UNDELIVERABLE); a refusal for a number that replied STOP (21610) is an opt-out, also when Twilio refuses at
  send time, and a send refused for an invalid or non-mobile number (21211, 21614) suppresses it. Listed in
  module-rate-limit.
• Opt-in confirmation: one text per number and website on its first subscription (first_for_address), claimed
  in Notification's delivery state; a daily cleanup. Never lost: a send refused for now (429/503 Retry-After) or
  failed before Twilio took it, a broker that is down and a lost message are retried by a 5-minute cron (8 attempts,
  then logged); one that may be out is never sent again.
• Reply order: Twilio's message webhook has no receive time; replies count when they arrive (Twilio does not
  retry them by default).
• Quiet hours in the recipient's time zone from the number (libphonenumber).
• A request that times out after it was sent is MessageSentException, so it is never sent twice.
