Conversation
Go 1.26.5 fixes CVE-2026-39822 (os: root escape via symlink plus trailing slash on Unix) and CVE-2026-42505 (crypto/tls), both of which are flagged by image scans against binaries built with Go 1.26.4. Updates the Go version in mise.toml (which CI derives its Go version from), go.mod, lib/go.mod, dev/vendor-lib.sh, and the Dockerfile builder image. The golang:1.26.5 Alpine image is only published on Alpine 3.23, so the builder stage moves from alpine3.22 to alpine3.23; the runtime stage is unchanged. ## Test Plan - go build ./cmd/src - go test ./... passes with Go 1.26.5
