The Smooooth release

This is a big release!

• Arbitrary text selection. You can now select text, and hit ctrl+c to copy it to the clipboard. This works just about everywhere, although there a re a few widgets were it isn't yet implemented.

• Smoother scrolling, for Kitty, Ghostty, and some other terminals.
• New content system
• Many fixes, see the full changelog below...

Breaking change: Strings returned from render() and other places will now be interpreted with Content.from_markup, rather than Rich.from_markup. This may result in slightly different colors, and emoji codes (like ":smiley:") will no longer be processed automatically. If you want to restore the old behavior you can return Rich.from_markup("Your output here") rather than string literal.

Why 2.0.0 ?

It took us more than 3 years to get to 1.0. But a couple of months to get to 2.0? Why?

We follow Semver which says that after 1.0, all breaking changes bump the major version number. We have some breaking changes here, which will be trivial to fix -- if they effect you at all. But a breaking change is a breaking change!
