Subject: [PATCH 2/2] Align CI Go versions with module requirements

Newer setup-go pins GOTOOLCHAIN=local, so matrix entries below the go.mod minimum now fail instead of silently upgrading the toolchain. Also: Go toolchains before 1.16 do not exist for darwin/arm64 (current macos-latest), and Go <= 1.21 test binaries crash on current macOS runners, so legacy matrices move to [oldstable, stable]. Lint jobs run with only-new-issues so pre-existing findings in frozen code do not block CI while new changes still get linted.
