/**
 * Hello-World example plugin source.
 *
 * Plugin authors write TypeScript / AssemblyScript / Rust against the
 * `@toolctrl/plugin-sdk` types, then compile to a single `.wasm` binary
 * with their toolchain of choice (wasm-pack, AssemblyScript's `asc`,
 * etc.). The host runtime treats the .wasm as opaque — only its
 * exports (`handleHello` here) and the `plugin.toml` manifest matter.
 *
 * Building this file to WASM is intentionally outside the scope of
 * the foundation: the `toolctrl plugin build` CLI is deferred (see
 * `docs/improvement-plan/06-plugin-system/wasm-sandbox.md` Deviations).
 * Operators wanting a working hello-world today can hand-compile via
 * AssemblyScript or use any other WASM toolchain that produces a flat
 * function export — the runtime contract is just `(arg) -> result`.
