chore(main): release cpp 0.1.0

[github-actions]

🤖 I have created a release beep boop

0.1.0 (2026-10-07)

⚠ BREAKING CHANGES

• core: prevent holes during SVG generation (#429)
• core: img2num::labels_to_svg now returns std::string instead of char*. Callers using the C++ API must update their code to capture the return value as std::string and remove any associated std::free / delete[] calls. Callers using the C binding (cimg2num) are unaffected at the ABI level but should use img2num_free_svg to deallocate the returned buffer.
• api: remove draw_contour_borders from labels_to_svg (#283)
