Security bump of the Go toolchain plus vulnerable module updates.

Advisories addressed

  • Go 1.27.3: CVE-2026-111943 (crypto/x509 now rejects certificate chains through the compromised eMudhra intermediates), plus the standard-library fixes from Go 1.27.2. The fix is compiled into each binary, so released binaries and images need a rebuild.

Changes

  • ./go.mod: toolchain go1.27.3
    • golang.org/x/sys v0.47.0 → v0.49.0

Verification (Go 1.27.3, linux/amd64)

  • go build ./...: pass
  • go test ./...: pass
  • govulncheck ./...: no vulnerabilities found
