v2.1.0

Version - [2.1.0]

Breaking

• Media duration is now a float (seconds) instead of an "HH:MM:SS" string,
  matching the updated API. Affects the media response models returned by
  media.list, manageVideos.get, media.getClips, liveStreams.listClips,
  manageVideos.update, media.updateSourceAccess, manageVideos.updateMp4Support,
  and the mediaList items in every playlist response.

Added

• enableRecording on live stream creation (inputMediaSettings); when omitted
  the API default (recording on) applies.
• accessRestrictions (domain and user-agent allow/deny policies) on live playback
  ID create/get and live stream playbackSettings.
• livePlayback.updateDomainRestrictions for
  PATCH /live/streams/{streamId}/playback-ids/{playbackId}/domains.
• livePlayback.updateUserAgentRestrictions for
  PATCH /live/streams/{streamId}/playback-ids/{playbackId}/user-agents.

Fixed

• Live validation harness now captures raw responses from the dev API host,
  not only the .com/.io hosts.

Tests & tooling

• Added an offline model-contract test suite (vitest, no credentials): media
  duration, enableRecording, and accessRestrictions serialization, and
  mocked-transport tests for the two new restriction endpoints.
• Added a full API-surface smoke test asserting every resource method exists.
• Added a return-type contract test asserting each resource method's declared
  return type matches the envelope class it deserializes.
• Added an async error-path test asserting 4XX/5XX reject with the typed error.
