Templates main moved 12 commits (PAY-35 module, ui-consumer lockfile,
recovery wave, X-708 profiles, deps). Verified: diff between pins contains
ZERO changes under ci/v2/reference-hooks/ (the G17 contract implementation),
so the bump is behaviour-neutral for the gate. release.yml
SIAX_TEMPLATES_PINNED_SHA and .siax/hook-pins.json templateRef bumped
together per the pin file's own reSyncInstructions.
