v0.22.0

New Features

• Chat SDK renderer: Added @json-render/chat to render specs as Chat SDK cards, so one catalog posts natively on Slack, Teams, and the other Chat SDK platforms. streamCard streams a card into a thread and edits it as elements arrive, and toCard validates specs against per-component schemas and optional platform limits. State expressions, visible, and repeat resolve against spec.state (#451)
• Chat SDK example: Added a playground that previews generated messages as Slack renders them, with a Teams Adaptive Card view and a copy button for Block Kit Builder (#451)
