wip: ProjectSpire agents, APIs, and card parser work
I’ve been working since last night and today with agents to document how Slay the Spire 2 works, prototype a Spire API and a REST API on top of it, and shape a WIP card parser that turns C# into JSON structures. That work is captured in ProjectSpire snapshot/2026-04-19, which gives me a concrete snapshot of the game model and tooling so far.
