chore(release): zero-pad CalVer month to match WebView convention

Anthias was tagged v2026.5.0 while the WebView component already
shipped three CalVer releases as v2026.04.0, v2026.04.1, v2026.05.0.
Standardise on the zero-padded YYYY.MM.PATCH form so the two
components sort consistently and stop drifting.
