feat(ralph): enhance Ralph Wiggum loop visualization

Add polished, animated Ralph Wiggum Loop panel with:
- Circular progress ring showing task completion percentage
- Task cards with status indicators (pending/in-progress/completed)
- Animated status badge with pulsing indicator when active
- Completion celebration animation with animated checkmark
- Smart time formatting ("1h 23m" instead of "1.38 hours")

Enhanced detection patterns based on official Ralph plugin:
- /ralph-loop command detection
- Iteration patterns: "Iteration 5/50", "[5/50]"
- Max iterations from YAML: "max-iterations: 50"
- TodoWrite tool output detection

Adds maxIterations field to InnerLoopState for tracking loop limits.
