[NineOfGaming]

Summary

Adds structured player profile/location lookup support, expands debug tooling, and improves plot state tracking.

Added

• Added /whois profile parsing with caching and timeout handling.
• Added public player lookup APIs:
  • FlintAPI.requestPlayerProfile()
  • FlintAPI.requestPlayerProfile(String)
  • FlintAPI.requestPlayerLocation()
  • FlintAPI.requestPlayerLocation(String)
• Added profile/location data models:
  • PlayerProfile
  • PlayerLocation
  • PlayerRanks
  • PlayerRank
  • PlayerRankCategory
  • PlayerBadge
• Added current user profile/rank state through Flint.getUser().getProfile() and Flint.getUser().getRanks().
• Added plot owner profile/rank state through Plot.getOwnerProfile() and Plot.getOwnerRanks().
• Added separate API opt-ins for confirmed location tracking, user profile fetching, and plot owner profile fetching.
• Added /flint debug controls for debug display, location confirmation, user profile fetching, and plot owner profile fetching.
• Added /flint test locate and /flint test whois commands with detailed debug output.

Fixed / Changed

• Replaced the internal locate result type with PlayerLocation so stored and requested location data use the same public model.
• Fixed plot dev origin calculation being offset.
• Fixed plot size detection caused by incorrect dev origin tracking.
• Fixed code-space bounds check.
• Improved underground code-space detection consistency.
• Fixed crash due to async locate, whois, and toast UI updates running off the client thread.

Documentation
