- Update Dockerfile base image from golang:1.24-alpine to golang:1.25.4-alpine (pinned by sha256 digest) to match go.mod requirement of go >= 1.25.4 - Fix gosec G703 (path traversal) false positives by adding filepath.Clean() at call sites with nolint annotations for internally-constructed paths - Fix gosec G704 (SSRF) false positive with nolint annotation; URL is already validated by validateURL() which checks scheme, resolves DNS, and blocks private IPs - All make check passes clean (lint + tests)
