matt 056351b8a6 feat(chat): implement subagent input and compact boundary display items
- Added support for rendering 'subagent_input' and 'compact_boundary' types in the chat display components.
- Introduced a new `MarkdownViewer` for displaying content in both item types.
- Enhanced the `MetricsPill` and `SubagentItem` components to include phase breakdowns and isolated usage metrics.
- Updated the `AIGroupDisplayItem` type to accommodate new item types and their properties.
- Implemented logic to compute and display token consumption across multiple phases for subagents.
