Summary

• Relocate update_cached_host_users() and update_cached_host_groups() calls outside per-PID loops to optimize and simplify code structure.
• Remove redundant updates within conditional blocks.

Summary by cubic

Refactored apps plugin aggregation to refresh UID/GID caches once per cycle instead of per process, removing redundant updates and reducing overhead. Simplifies control flow by moving cache updates before the PID loop.

• Refactors
  • Call update_cached_host_users() and update_cached_host_groups() once before iterating PIDs (guarded by PROCESSES_HAVE_UID/GID).
  • Removed duplicate updates inside UID/GID branches.
  • No change to target selection or aggregation behavior.
