Summary: Refactors the Dockerfile from a single-stage Alpine image to a multi-stage build producing a minimal scratch image with a statically-linked Go binary.

Issues: None blocking, but note one change worth awareness:

💡 LOW - Dockerfile:5 - Undocumented Go version upgrade

The Go version was upgraded from 1.24.2-alpine to 1.26-alpine. While Go maintains backward compatibility, this skips versions 1.25. Consider verifying compatibility or documenting this upgrade rationale.

Recommendations:

💡 Dockerfile - Optional improvements

Step 1: If the application uses time zones (e.g., time.LoadLocation()), add timezone data:
COPY --from=builder /usr/share/zoneinfo /usr/share/zoneinfo
ENV TZ=/usr/share/zoneinfo
Step 2: Consider pinning the exact Alpine version for reproducibility:
FROM golang:1.26-alpine3.19 AS builder

Score (Code Quality): 88

Result: 👍 Good

The multi-stage build approach is a solid improvement—static linking combined with a scratch base significantly reduces image size and attack surface. The CA certificates are correctly included for TLS functionality. The Go version upgrade (1.24.2 → 1.26) should work but warrants a quick compatibility check.
