Subject: [PATCH] fix: statically import zstd glue so inline workers are
 self-contained

Inline workers (Vite ?worker&inline) run from blob: URLs, where the
runtime relative import("./wasm-zstd.js") cannot be resolved, breaking
consumers bundled with Next.js Turbopack ("Failed to resolve module
specifier './wasm-zstd-*.js'"). Import the Emscripten glue statically so
bundlers inline it into the worker chunk, making the worker fully
self-contained.

Bump to 1.1.2.

+Vite inline workers are loaded from `blob:` URLs, so neither sibling `.wasm` files nor sibling
+JS chunks can be resolved relative to the worker. To keep inline workers self-contained, the
+Emscripten glue is imported **statically** (not via a runtime `import("./wasm-zstd.js")`), so
