The bindings under src/wit are generated from the pumpkin-plugin-wit submodule by tools/gen.zig. The canonical ABI is handled at comptime in src/abi.zig, so plugins are plain wasm32-freestanding modules and only need wasm-tools to become a component. On top of that there is a small hand written layer: plugin registration, typed event handlers, declarative commands (cmd), text components from struct literals (msg) and std.log support.
