[Unreleased]

Webhook handling spec helpers (CHA-2961): UnknownEvent class for forward-compat; GunzipPayload, DecodeSqsPayload, DecodeSnsPayload primitives; ParseEvent (returns typed event or UnknownEvent); VerifyAndParseWebhook HTTP composite; ParseSqs / ParseSns queue composites (no signature — backend emits no HMAC for queue messages today; queue transports are secured via AWS IAM access controls). Transparent gzip via magic-byte detection.
New exception class: Webhook.StreamInvalidWebhookException — unified failure type for signature mismatch, invalid JSON, missing/non-string type field, gzip decompression failure, base64 decode failure, or malformed SNS envelope.
New instance methods on StreamClient (via BaseClient): VerifySignature(body, signature) and VerifyAndParseWebhook(body, signature) — drop the secret parameter in favor of the client's stored API secret. Dual API: static Webhook.* methods that take an explicit secret remain available.
New instance methods on StreamClient (via BaseClient): ParseSqs(string), ParseSns(string) (no signature; AWS IAM).
Conformance fixture suite under tests/fixtures/webhooks/.

Type names across all products now follow the OpenAPI spec naming convention: response types are suffixed with Response, input types with Request. See MIGRATION_v5_to_v6.md for the complete rename mapping.
Event (WebSocket envelope type) renamed to WSEvent. Base event type renamed from BaseEvent to Event (with field type instead of T).
Event composition changed from monolithic *Preset embeds to modular Has* types.
Pager renamed to PagerResponse and migrated from offset-based to cursor-based pagination (next/prev tokens).

Full product coverage: Chat, Video, Moderation, and Feeds APIs are all supported in a single SDK.
Feeds: activities, feeds, feed groups, follows, comments, reactions, collections, bookmarks, membership levels, feed views, and more.
Video: calls, recordings, transcription, closed captions, SFU, call statistics, user feedback analytics, and more.
Moderation: flags, review queue, moderation rules, config, appeals, moderation logs, and more.
Push notification types, preferences, and templates.
Webhook support: WHEvent envelope class for receiving webhook payloads, utility methods for decoding and verifying webhook signatures, and a full set of individual typed event classes for every event across all products (Chat, Video, Moderation, Feeds) usable as discriminated event types.
Cursor-based pagination across all list endpoints.
