Build and scan with Go 1.26.10

govulncheck started failing CI on GO-2026-6809, a crypto/x509 flaw in the
standard library that is fixed in 1.26.10 and reachable through
http.Server.ListenAndServe. golang:1.26.9 is what ci.yaml, release.yaml and
the Dockerfile build with, so all five pins move together: the scan and the
shipped binary must agree on the toolchain, as in 3173abf.

No code change; go.mod still says go 1.25.9.
