Consolidates SOU-1068, SOU-1069, SOU-1071 into this PR (already addressing
SOU-1070 / CVE-2026-44457). Same hono 4.12.14 -> 4.12.18 bump fixes all four.

Per the updated convention in CLAUDE.md (one CHANGELOG line per PR, not
per CVE), the four sibling hono CVEs share one comma-separated entry.

- Line 15: Update the CHANGELOG entry for the hono bump (^4.12.18) to only claim
CVEs actually fixed by that release: remove CVE-2026-44455 and CVE-2026-44458
from the list, and either omit CVE-2026-44456 or note it was fixed in 4.12.16
(not newly resolved by 4.12.18); keep CVE-2026-44457 as the sole CVE attributed
to 4.12.18 and preserve the PR reference and version string ("hono" and
"^4.12.18") in the entry.
