MGS Origins Expanded 3.5.0 — Engine Overhaul

This release adds a real Forge Java gameplay layer on top of the existing Origins/Apoli data pack.

Core systems:
- Profile-aware stealth for Solid Snake, Venom Snake, Quiet, The End, Sniper Wolf, Old Snake, Gray Fox and Decoy Octopus.
- Sneak camouflage plus ParCool crawl detection via the server-side SWIMMING pose.
- Stealth breaks on player attacks, projectile launch and incoming damage; combat heat controls re-entry.
- The End reconnaissance uses one owned ground parrot at a time and never spawns a replacement when a shoulder parrot exists.
- Ground duplicates are removed; a lone scout is teleported back when it gets too far away.
- Hostiles in a 32-block radius are given Glowing for 100 ticks (5 seconds), refreshed every second.
- Hostile detection includes vanilla Enemy mobs plus aggressive/targeting modded Mobs.
- Engine state is exposed through player tags for future Origins/KubeJS/Epic Fight bridges:
  mgscanon_engine_stealth
  mgscanon_engine_crawl
  mgscanon_engine_sneak_camo
  mgscanon_engine_heat_high
  mgscanon_engine_recon
