Wraps children in React's ViewTransition (canary API) when available,
falling back to Fragment in environments where ViewTransition is undefined
(test env, stable react-dom). Add react/canary to tsconfig types to
expose the ViewTransition component type.
Add html-react-parser-backed RichText component that converts HTML
strings from PocketBase rich-text fields into React elements without
dangerouslySetInnerHTML. Replace raw <p> render in IntroSection and
BioSection, and drop the invalid slug filters those collections lacked.
