Initial Mintlify docs

  • Added product-oriented Mintlify docs structure.
  • Added SDK guides for iOS, Android, Flutter, and React Native.
  • Added catalog setup, testing, recovery, and platform support docs.
  • Embedded docs under /docs in the AppActor web app.

Product workflow expansion

  • Split Remote Config, Experiments, Apple Ads, and Attribution into product workflows plus SDK reads.
  • Documented AppActor-owned Remote Config rules, scopes, cache behavior, and launch testing.
  • Documented AppActor-owned experiment assignment, traffic allocation, lifecycle, and analysis metrics.
  • Added Apple Ads dashboard integration and analytics pages.
  • Renamed API Reference navigation to SDK Reference because these pages document client SDKs, not public REST APIs.
