queue: withdraw our own "stable source" claim about the site root (three digests at two sizes today)

The tick above corrected Merlin's check-in sentence but left our earlier claim standing: this file
calls https://www.stackchainmagazine.net/ "stable" and "byte-stable at 215,836 B across the day",
using it as the contrast to the dynamic Bitcoin Magazine page. It is not stable across the day.
Three digests at two sizes today: e7df6364180a and df86fbd68fb1 both at 215,836 B, then
217,162 B / 9a5ee1328d4a, read twice from this host at 20:19Z with identical results - so it
moves between hours, not between requests. Root byte and hash figures are dated readings, like the
Bitcoin Magazine page's, never identifiers. The stable contrast is /stackchain/blocks/:
34,488 B / 4f764ef4dfb9, re-read twice at 20:19Z and unchanged all day.

Also verified this tick and unchanged: docs/q13-fix-pack.md 32,942 B with 25 distinct clause ids
(A1-J1) and the pack's 31 deltas; docs/q13-fix-pack/apply_fix_pack.py 25,361 B, unrun; the build
tree at its before-hashes (blocks.json 63c9cee6103a, build_blocks.py 97fedb5dd5e8) with 0 files
newer than 18:00.
