v13.6.0

• If compute cover at combat start is enabled and using PF2e Visioner as visibility handler, call getAutoCoverState to get the updated cover status when testing observers vs avoiders.
• Add an opt-in strict mode game setting.
  • I do not recommend enabling this because I'm not going to chase the numerous visibility edge cases and feats that might affect this.
  • I likely won't respond to any bug reports related to something showing up that shouldn't have when strict mode is enabled.
  • Requires avoiders to have explicit cover or concealment conditions from observing tokens in order to become hidden or undetected from them.
  • If there is interest I might create a Hook allowing others to filter the results prior to application to initiative cards or visibility managers.
