Function joinJsChunks

packages/core/src/compiler/htmlBundler.ts:579–585

* Concatenate JS chunks safely. Goals: * - Each chunk's last statement is terminated, so joining can't introduce ASI * surprises (e.g. `a()` followed by `(b)()` — the second chunk would parse * as a call on the first's return value). * - In the common case (chunk already ends with `;

(chunks: string[])

 *     comment, and the standalone `;` becomes the statement separator.
