Offload functions to worker threads with shared memory primitives for Node.js.
fix: resolve worker-entry extension from import.meta.url
Published 1.0.0 threw "Cannot find module .../dist/worker-entry.ts"
because the worker entry URL was hardcoded as a string literal. tsc's
extension rewriting only handles import specifiers, so .ts leaked into
dist/*.js. Now derived from import.meta.url — src picks .ts, dist picks .js.

Fix `Cannot find module .../dist/worker-entry.ts` when consuming the published build. The worker entry URL was hardcoded to `./worker-entry.ts` as a string literal, so tsc's extension rewriting (which only handles import specifiers) left it unchanged in `dist/*.js`. Now derived from `import.meta.url` so src uses `.ts` and dist uses `.js`.
