chore(main): release 2.0.0

[alex-feel]

🚀 New Release

2.0.0 (2026-06-17)

⚠ BREAKING CHANGES

• Custom Components v2 requires Streamlit >= 1.56 and Python >= 3.10 (previously Streamlit >= 1.45 and Python >= 3.9). The component is now frameless (no iframe); the public copy_button() signature and return value are unchanged.

Features

• migrate to Streamlit Custom Components v2 and fix horizontal layout (1831952), closes #27

Bug Fixes

• embed the frontend bundle inline instead of via an asset_dir manifest (34478f8)
• include the frontend bundle as a wheel artifact instead of a force-include so editable builds don't require it (d6f0036)
