chore(main): release packages-js 0.1.0

[github-actions]

🤖 I have created a release beep boop

0.1.0 (2026-08-03)

⚠ BREAKING CHANGES

• js: img2num no longer offloads WASM execution to a background thread automatically. Heavy operations (gaussianBlur, bilateralFilter, kmeans, imageToSvg) now run on whichever thread calls them. This can block the calling thread (browser main thread/UI or the Node event loop during processing. Consumers who need non-blocking behavior must now wrap calls in their own Worker or worker_thread.
• core: prevent holes during SVG generation (#429)
• api: remove draw_contour_borders from labels_to_svg (#283)
