📦 SDK + Scanner versioned releases · SemVer · No silent ship

Release notes — every version, every change.

SemVer for the SDK. Date-tagged scanner builds for the web. Every release links back to the corresponding phase in /changelog. If we change behavior in production, the change shows up here within the same hour. No silent ship — that's the rule.
