/**
 * An `encode` implementation for {@link ExternalBundleWebpackPlugin} that emits
 * a **web binary bundle** (the `.web.bundle` format decoded by
 * `@lynx-js/web-core`) via `@lynx-js/web-core/encode`, instead of the native
 * TASM format produced by `@lynx-js/tasm`.
 *
 * Differences from the native encoder, all required by the web platform:
 * - Sections are routed to the bundle slot whose chunk format they match,
 *   instead of all going into custom sections, keyed by the `encoding` tag
 *   `ExternalBundleWebpackPlugin` sets from each chunk's layer: the main-thread
 *   chunk (`JsBytecode`) goes into `lepusCode`, every other JS chunk into
 *   `manifest`, and `CSS` chunks into the StyleInfo section. The web runtime
 *   then loads each through the same path the card uses for its own
 *   lepus/manifest chunks.
 * - JS is kept as **raw source** — the `JsBytecode` tag only selects the slot;
 *   the chunk is not bytecode-compiled. The web runtime wraps each section when
 *   `lynx.loadScript` evaluates it, so the build must not wrap it here.
