2.3.1 RC1

Release candidate for 2.3.1, built from main at 8d5bf1e. Install pattern-builder-2.3.1-rc1.zip from Plugins → Add New → Upload Plugin.

• Agents give each color they add to your design system a name for the job it does (base, surface, primary, accent, hairline and so on) rather than its hue, so a restyle never leaves a color misnamed, and a name outside that list is refused.
• Font sizes added by agents are limited to x-small, small, medium, large and x-large; heading sizes are set on the headings themselves, and other text takes the nearest of the five.
• Reproducing an existing site maps its colors and type onto those names instead of copying the source's own.
• Agents describe a pattern in one sentence saying what it is for and roughly what is in it, and saving a pattern warns when a description runs longer.
• Fixed: synced patterns kept in folders inside the theme's patterns folder, as every pattern installed from the cloud is, were inserted into the editor as copies instead of staying linked.

Testing notes

• Moving to the final release: this build reports version 2.3.1, the same as the final release, so WordPress won't offer 2.3.1 as an update to a site running it. Reinstall the final release over it.
• Deleting the plugin: this zip doesn't include uninstall.php, so deleting the plugin leaves its options and cached data behind.
