Capsule: Fine-grained isolation for multi-agent systems using WASM

Hi there, Author here!

I started building Capsule because I hit a wall with existing Python agent frameworks (fragile loops, lost state, no sandboxing). I felt we needed a proper infrastructure layer for this.

This is an RFC / Architecture Preview. I'm currently implementing the core engine in Rust (publicly), but I wanted to share the design philosophy first.

I'd love to hear your thoughts on the Python API design (@task decorators) or the Wasm isolation approach!
