v1.29-notify-4: bump Go toolchain minimum to 1.26
Raises the minimum Go required to build scoutfs-notifyd to 1.26 (current upstream Go as of Feb 2026). The source uses no language features beyond basic stdlib; the bump is a policy decision to track current Go rather than a technical need. No distro currently packages Go 1.26 in its stable repos, so scoutfs-build's CI now fetches the official linux tarball from go.dev and caches it in /var/cache/scoutfs on the runner host (keyed by version + arch). Builds remain hermetic after that single fetch: CGO_ENABLED=0, GOPROXY=off, no module dependencies. Changes: utils/notifyd/go.mod go 1.21 -> go 1.26 utils/scoutfs-utils.spec.in golang >= 1.21 -> golang >= 1.26 The kmod patches (1 and 2) and the daemon source are unchanged.

On top of the stock scoutfs build requirements, patch 3 adds:

* `golang >= 1.21` on the build host (RHEL/EL9: `golang`, EL8: `go-toolset`).

Debian 12 / Ubuntu 22.04+: `golang-go`.

build time. `CGO_ENABLED=0` so the produced binary is a pure-Go static
