Fixed incorrect path-component splitting in URL-to-filename conversion where A (the path array) was referenced as z in certain code paths, causing incorrect encoding of URL path segments (search for "A.split" in the URL path normalizer — nJ structural change at line ~11580).
Fixed loadMarkdownFilesFromDir timeout log message which incorrectly reported the function name as loadMarkdownFiles (search for "loadMarkdownFilesFromDir: ripgrep timed out scanning").
