ci: drop redundant kclipper:format from validate

go:lint (golangci-lint run) already reports unformatted Go and fails,
and kclipper:lint-prettier already gates yaml/md/json formatting.
kclipper:format re-ran a full golangci-lint pass with --fix purely to
assert the same formatting freshness, so validate ran golangci-lint
twice over the whole tree concurrently on a 4-core runner. Under that
contention a cold run exceeded golangci-lint's 5m timeout (exit 4), and
because the run never completed the linter cache never warmed, so
go:lint and kclipper:format both failed at ~5m35s on every push and PR.

Drop kclipper:format from the check list: go:lint and
kclipper:lint-prettier cover its gating, while go:generate and go:tidy
remain for generator freshness. The +generate Format function is
unchanged and still applies fixes under `dagger generate` and the
pre-commit hook.
