Genkit JS 1.19.3

• chore(js): update lots of READMEs to deep link to genkit.dev by @mbleigh in #3562
• chore: Adds .guides folders to a few Genkit packages by @mbleigh in #3614

Dev UI Changes

Messages now render within traces. A fix prevents border colors from incorrectly changing on read-only messages, and another stops images from breaking out of their message cards. Section headers for inputs/outputs are now collapsible, media URLs render directly as returned from flows, and the collapse/expand controls are limited to JSON content, no longer appearing for previews.
