Unify the visual and interaction rules on top of the v7 redesign.
- Theme color #F97315 for --action-* and --ring; dark mode uses #EA580C
with white text, toned-down mode colors and translucent soft fills
- Buttons mapped to three sizes (28 / 32 / 36); inputs, selects and
search fields share fieldClass; self-drawn checkbox and radio
- HoverTip replaces title on about 100 icon buttons; it stays closed
when a closing menu returns focus to its trigger
- Install tailwindcss-animate so menu, popover, dialog and tooltip
enter/exit animations take effect; sliding segment thumb and tab
underline
- Remove the command palette and the header prompt entry; provider card
primary actions become icon buttons
- Virtualize the session list and the Skills discovery list; optimistic
toggles for MCP and Skills with a 300ms delayed disabled state
- Toasts drawn unstyled with status-colored icons and de-duplicated
- Windows: hide the system title bar and use in-app window controls;
macOS: brand row under the traffic lights
- Focus rings only for keyboard users
- Skills discovery and the prompt list show the last result from a
local cache and refresh in the background
- Drop the trailing ellipsis from 36 dialog-opening labels
- Provider list fills the main area
