Progression Tree Builder for Game Creator 2

------------------------------------------------------------------------------

Progression Tree Builder extends Game Creator 2 with a complete progression system: multi-layered skill trees — passive bonuses, active abilities, ranked upgrades, mutually exclusive choices and dependency chains — authored in a node-based editor and driven from the same Instructions and Conditions as the rest of your game. 

Every tree is also a roguelite upgrade pool: switch a tree to Latest Mode and it becomes a weighted "pick 1 of 3" level-up screen (own example scene plus a Roguelike template tree), with per-skill weights, per-tier balancing and a Refresh Latest Pool instruction; pools save and restore with the rest of progression.

Core:

• Root/Passive/Active/Choice skill types
• 1–10 ranks with per-rank cost scaling; Flat, Percentage or Per-Rank stat modifiers through the GC2 Stats module
• cooldowns and Attribute-based activation costs
• choice groups
• tree unlock and respec costs paid from a GC2 Attribute
• optional item/currency skill costs via the Inventory Bridge
• optional shared point pools across trees

GC2 integration: 12 Instructions, 8 Conditions, 1 Property (Progression Tree), and full Remember save/load — unlocked skills, ranks, points, cooldowns and Latest Mode pools all persist, with stat bonuses rebuilt automatically on load.

New this cycle:

• OR / "any N of" prerequisites (default stays All)
• "why is this skill blocked?" reason shown on the tooltip and detail panel, also available as an API call
• rank-gated connections (enforcement opt-in)
• A runtime pan & zoom viewport component
• One-click Auto Arrange button;
• item/currency skill costs via an optional Inventory Bridge
• shared point pools across two or more trees

Fixed this cycle (behaviour change — please read):

Tree Unlock Cost and Respec Cost were advertised in the docs and inspector but never actually charged — they now are. A cost of 0, an empty currency field, a missing Traits component, or an unknown Attribute all resolve to "free," so no existing project gets locked out by the fix.

Respec and Lock now really remove the stat modifiers a skill granted, instead of leaving them applied forever. Stat bonuses are correctly re-applied when a save is loaded. Player builds, previously broken by two editor scripts compiled into runtime assemblies, now succeed.

Works with: Game Creator 2 (Core) + Game Creator 2 Stats — both required.

Inventory is optional.
