Brings the shared SDK up to the fuller client chat-web had vendored, so frontends consume one source of truth instead of copying it: - types: Message gains senderId/senderName/attachment/parentInteractionId/ annotations; add Attachment, AnnotationGroup, AnnotationEvent, ThreadSummary, SavedItem, LoginResult; MessageEvents gains `annotation`; SocketLike gains connected + optional timeout. - MessageSocket: onConnected, openThread(opts), richer sendMessage(opts) (attachment/mentions/parentInteractionId, back-compatible with contentRef), pin/save/react via annotate, focus, reconnect-re-subscribe-all. - RestClient: login, listUsers, listThreads, createThread, listSaved, addParticipant. Bump 0.1.0 -> 0.1.1. Whole monorepo still builds (Message change is additive for iios-message-web/iios-support-web/demos). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
