Subject: [PATCH] fix(tier-check): count an SDK release in the 24h before a
 spec release as tracking it

Lockstep SDKs publish in the hours before the spec release is tagged
(for 2026-07-28: python-sdk 3h early, go-sdk 3.5h, typescript-sdk the
evening before), so "first SDK release at or after the spec" read them
as not having released and would fail them 30 days later. Allow a 24h
lead.
