♻️ refactor: migrate AI Rules to Claude Code Skills system

Migrate all AI Rules from .cursor/rules/ to .agents/skills/ directory:
- Move 23 skills to .agents/skills/ (main directory)
- Update symlinks: .claude/skills, .cursor/skills, .codex/skills
- Create project-overview skill from project documentation
- Add references/ subdirectories for complex skills
- Remove LobeChat references from skill descriptions
- Delete obsolete .cursor/rules/ and .claude/commands/prompts/ directories

Skills structure enables better portability and maintainability across AI tools.

Use Transitions for Non-Urgent Updates

Mark frequent, non-urgent state updates as transitions to maintain UI responsiveness.

Incorrect (blocks UI on every scroll):

function ScrollTracker() {
  const [scrollY, setScrollY] = useState(0)
  useEffect(() => {
    const handler = () => setScrollY(window.scrollY)
    window.addEventListener('scroll', handler, { passive: true })
    return () => window.removeEventListener('scroll', handler)
  }, [])
}

Correct (non-blocking updates):

import { startTransition } from 'react'

function ScrollTracker() {
  const [scrollY, setScrollY] = useState(0)
  useEffect(() => {
    const handler = () => {
      startTransition(() => setScrollY(window.scrollY))
    }
    window.addEventListener('scroll', handler, { passive: true })
    return () => window.removeEventListener('scroll', handler)
  }, [])
}
