SLOP State Layer for Observable Programs

AI agents either parse screenshots (expensive, lossy) or make blind tool calls (no context). SLOP fixes this: apps expose a semantic state tree that AI subscribes to with incremental updates. Actions are contextual: they live on the nodes they affect and appear/disappear as state changes. Ships with a 13-doc spec, 14 SDK packages (TypeScript, Python, Rust, Go), React/Vue/Svelte/Solid/Angular adapters, Chrome extension, desktop app, and CLI. MIT licensed. State-first, not action-first.
