- Cut broad render fanout across the app by replacing shared-store whole-object subscriptions with leaf selectors, memoizing hot chrome boundaries, and isolating disabled global providers from live session/message state. This keeps header controls, composer toolbars, side panels, and other non-hot UI surfaces from repainting on every assistant update or keystroke.
- Rework sidebar session ordering so recent, project groups, and worktree groups derive from one ordering source while avoiding streaming-time thrash. The sidebar now uses a stabilized session snapshot, preserves structural identity for unchanged rows, reads live row status/details per session, and applies a one-shot sort bump on idle->busy instead of continuously resorting during activity.
- Fix chat/input scroll instability by separating viewport-resize handling from message-growth handling, disabling conflicting native scroll anchoring, and stopping textarea autosize from collapsing on every growth keystroke. This removes the multiline typing jiggle during streaming and reduces unnecessary composer rerenders.
- Also gate voice context wiring behind voice-mode enablement and codify the learned render/scroll/order anti-patterns in AGENTS.md so future changes avoid the same classes of regressions.

- Three modes: collapsed, activity (summary), detailed
- Applies to activity groups and individual tool calls
- Configurable in Appearance Settings
- **Font Size & Spacing Controls**: Adjustable typography and layout density
- Font size: 50-200% scaling of all semantic typography
- Spacing/padding: 50-200% scaling of margins, gaps, line heights
- Real-time preview with reset buttons
- Settings in Appearance Settings
- **VSCode Extension Settings View**: Full settings access in VSCode extension
- Add settings navigation and view type
- Settings button in header
- Navigate between sessions, chat, and settings
Technical changes:
- Enhanced useUIStore with new state management
- Dynamic CSS variable scaling for typography and spacing
- Typography helper functions for variable access
- ThemeProvider integration for auto-applying scales
* fix: hide theme mode in VSCode and fix detailed tool expansion
- Hide "Theme Mode" setting in VSCode extension settings as VSCode
dynamically applies its own theme to the extension
- Fix bug where tools from subsequent messages in a turn weren't
expanded when "Detailed" mode was selected
- Now correctly aggregates all tool IDs from turnGroupingContext when
calculating effective expanded tools for progressive groups
