Interactive playground for animating the Shell tool subtitle ("submessage") in the timeline trigger row.

### Production component path
- Trigger layout: \`packages/ui/src/components/basic-tool.tsx\`
- Bash tool subtitle source: \`packages/ui/src/components/message-part.tsx\` (tool: \`bash\`, \`trigger.subtitle\`)

### What this playground tunes
- Width reveal (spring-driven pixel width via \`useSpring\`)
- Opacity fade
- Blur settle`,
