Conversation
This commit introduces a new inline streaming system for ACP agents that displays assistant messages incrementally with proper word wrapping before committing them to the scrollback buffer. Key changes: - Add BackendEvent enum to wrap ConversationEvent and inline events - Implement InlineEntryState for tracking streaming text with wrapping - Add text_utils module with wrap_text_to_width function - Update all backends to emit BackendEvent instead of ConversationEvent - Track inline entries in Model and render them in UI - Update tests to handle new BackendEvent structure Benefits: - Assistant messages now appear immediately as they stream - Proper word wrapping adapts to terminal width changes - Cleaner separation between streaming and committed content 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- handle AgentThoughtChunk updates and emit thinking entries - track separate assistant/thinking buffers with commit/abort-all helpers - adjust history types and inline tracker test coverage
