Activate Slack's assistant pane and native streaming as the default experience,
with zero config and safe degradation. The portable surface lands in
@copilotkit/bot (onThreadStarted lifecycle, capability-gated
thread.setSuggestedPrompts/setTitle, two SurfaceCapabilities flags + optional
adapter methods); @copilotkit/bot-slack adds the Bolt Assistant middleware
(assistant.ts), the chat.startStream transport with automatic legacy fallback
(native-stream.ts), a per-thread no-double-delivery listener guard, and
renderer pane-status mode. Everything degrades, never throws.
Pure JSX runtime (no React, no Slack) producing a BotNode IR tree.
Statically typed component props via a package-owned JSX namespace:
unknown attributes, bad values, and bad children are compile errors.
Components: Message, Header, Section, Markdown, Field, Context,
Actions, Button, Select, Input, Image, Divider; bind() escape hatch
for non-serializable handler captures.
