* chore(ai-workflow): track repo-managed review tooling

* fix(ai-workflow): remove repo-specific path assumptions

Use Activity Component for Show/Hide

Use React's <Activity> to preserve state/DOM for expensive components that frequently toggle visibility.

Usage:

import { Activity } from 'react'

function Dropdown({ isOpen }: Props) {
  return (
    <Activity mode={isOpen ? 'visible' : 'hidden'}>
      <ExpensiveMenu />
    </Activity>
  )
}

Avoids expensive re-renders and state loss.
