v0.1.0

First release. A thin, zero-dependency wrapper over the
Mailtea REST API, built on
net/http and json from the standard library. Ruby 3.0+.

Added

• Mailtea::Client — reads MAILTEA_API_KEY and the optional
  MAILTEA_API_BASE_URL, or takes both explicitly. The HTTP transport is
  injectable, so tests need no network and an app can route requests through its
  own instrumented stack.

• Transactional email. emails.send, batch, get, list, analytics,
  update, reschedule and cancel — plus emails.inbound for received mail
  (list, get, reply, and attachments.list / attachments.get).
  emails.get adds a status alias of the wire's last_event. The API caps a
  message at 50 recipients combined across to, cc and bcc.

• Audience. contacts (create/upsert, list, get, update,
  delete), segments, topics, senders, suppressions (including
  export, which returns raw CSV text), and contact_properties.

• Content. posts (create, send, send_test, list, get, update,
  delete), templates (including render, publish/unpublish, versions,
  restore_version and duplicate), and assets for the publication's image
  library — raw bytes are base64-encoded for you.

• Platform. domains (+ domains.tracking), webhooks, api_keys,
  automations, automation_runs, events and event_definitions.

• Mailtea.verify_webhook_signature / Mailtea.sign_webhook — Standard
  Webhooks verification with replay protection and a constant-time compare,
  checked in the test suite against signatures produced by the platform's own
  TypeScript signer.

• Mailtea::Error on every failure, carrying status (0 for a client-side
  fault such as an unreachable API), message, code, details and
  request_id.
