v1.5.1 — moved to the Quicgate organization

The project now lives in its own GitHub organization: Quicgate/quicgate.

Changed

• Container image is now ghcr.io/quicgate/quicgate (:1, :1.5, :1.5.1, :latest). The old ghcr.io/maferick/quicgate path stops receiving updates — repoint your image: to the new one.
• All links updated to the new org. The old maferick/quicgate URL auto-redirects.

No functional changes to the binary.
