gosu doesn't publish proper Go module semver tags, so `go install github.com/tianon/gosu@v1.19` fails with "no matching versions". Replace the multi-stage golang builder with `COPY --from=tianon/gosu /gosu /usr/local/bin/gosu`, which pulls the pre-built binary from the official tianon/gosu Docker image. This image is rebuilt with recent Go toolchains, so it still addresses the Go stdlib CVEs documented in the Dockerfile comments. Fixes #363 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# Override the base image's gosu binary with the latest from tianon/gosu.
|

# The postgres base image bundles gosu built with Go 1.24.6, which contains:
|
|
# - CVE-2025-68121 (CRITICAL): crypto/tls vulnerability
|
|
# - CVE-2025-58183 (HIGH): archive/tar unbounded allocation
|
|
# - CVE-2025-61726 (HIGH): net/url memory exhaustion
|
|
# - CVE-2025-61728 (HIGH): archive/zip CPU exhaustion
|
|
# - CVE-2025-61729 (HIGH): crypto/x509 DoS
|
|
# - CVE-2025-61730 (HIGH): TLS 1.3 handshake vulnerability
|
|
# The tianon/gosu image is rebuilt with recent Go toolchains, eliminating these CVEs.
|
|
# Using COPY --from avoids `go install` failures (gosu lacks semver Go module tags).
