MGS Origins Expanded -- Canon Effects Refinement
Files changed: startup_scripts/mgs_custom_effects.js, server_scripts/mgs_api_runtime.js, assets/kubejs/lang/{en_us,pl_pl}.json
Effect IDs, textures, badges and every other script are unchanged. Restart Minecraft after replacing startup scripts.

CANON FIXES
- Emma: removed water breathing / night vision in water (she is aquaphobic; the jar's Aquaphobia power punishes water). Now: Haste on dry land. Renamed "Hacker's Focus".
- Fortune: deflection now only affects projectiles and explosions (was: any hit, including melee). The roll now happens before the cooldown is spent (a failed roll no longer burns the cooldown). 12% normally, 35% below 35% HP.
- Mei Ling: Soliton Radar -- Speed when hostile mobs are within 10 blocks (was: generic night vision + random water breathing).
- Otacon: crouch to pilot the Metal Gear Mk. II -- tags up to 6 hostile mobs within 16 blocks with Glowing, 15s cooldown (was: generic night vision).
- Psycho Mantis: floats -- slow falling while airborne (was: night vision, which his Psychic Perception power already gives).
- Gray Fox: optical camouflage -- crouch = invisibility + speed (his stealth powers are not attached to the origin). Removed the sprint-strength copy shared with Raiden and Sam.

DE-DUPLICATION (the effect was stacking on a power that already does the job)
- The End: effect no longer heals (Sun-Bound Recovery power does). Now: crouch = night vision at the scope.
- Vamp: effect no longer lifesteals (CQC Recovery + High-Speed Regeneration already heal). Now: Resistance pulse below 35% HP; kept water breathing and the on-hit speed tempo.
- Granin, Sunny: dropped night vision (no canon basis / Sunny has Night Operations). Haste kept.

BUG FIXES
- Decoy Octopus, Quiet, Sniper Wolf: no longer strip invisibility / slowness that came from other sources (potions, enemies). Their own short effects expire in under a second.

KEPT AS-IS (already fit canon): Armstrong, Big Boss, Solid Snake, Old Snake, Venom Snake, The Boss, Raiden, Jetstream Sam, Liquid, Solidus, Sundowner, Monsoon, Volgin, the Cobra unit, Sniper Wolf, Quiet, Meryl, Campbell, Kaz, Naomi, Para-Medic, Rosemary, Drebin and the rest.
