sync: builtin catalog 20 → 25 tools (#2)

Regenerate scaffold from private main (0be1055) and bring the public
catalog in sync. Adds 5 builtins:
- qrcode-generate (QR code → SVG, byte mode ECC-L, v1-v10, pure JS)
- image-data-url-inspect
- youtube-url-normalize / youtube-oembed-read / youtube-info-format

source digest sha256:6ebd1d8e… → sha256:54efa168…
scaffold digest sha256:97c6d108… → sha256:e2b2980b…
