MGS Origins Expanded 3.7.0 — Progression Engine

- Fixes the Forge dependency comparison bug: Apoli 1.20.1-2.9.0.8 is accepted explicitly.
- Requires the uploaded Pufferfish Attributes 0.8.2, Skills 0.19.1 and Skills x Origins 0.2.1 addons.
- Adds six role skill trees plus universal Fieldcraft progression.
- Origin-specific categories are unlocked through puffish_skills_origins:unlock_category.
- Skill rewards use Pufferfish Attributes: stamina, melee_damage, ranged_damage, sword_damage, stealth, resistance and other registered attributes.
- Keeps the prior MGS stealth, recon/parrot, VFX, Native Epic Fight, WOM, TaCZ and ParCool layers.
- TEcho is not a dependency.
