ci: release-macos workflow (dispatch); retire macOS smoke-test

The macOS release leg: workflow_dispatch (tag input) on the Tart runner — test → build both *-apple-darwin targets → rewrite nix libiconv to /usr/lib + ad-hoc re-sign → upload binary + .sha256 to the tagged release (idempotent create-or-get) → prune the nix store by generation. Composed entirely of parts the smoke-test proved green, so the smoke-test is removed. Dispatch-only fits the intermittent runner and keeps the 4-target Linux/ Windows release independent. Becomes triggerable once CI is on the default branch (workflow_dispatch is default-branch-only in Gitea).

+# macOS release leg — the two *-apple-darwin binaries, built natively on the
+# Tart (Apple-Silicon) runner and attached to an existing Gitea release.
+#
+# Manual dispatch only: the Mac runner is intermittent, so this is triggered by
+# hand (with the Mac up) for a given release tag. The 4-target Linux/Windows
+# release (release.yaml) runs on the tag itself and never waits on the Mac, so a
+# release always has those four; the macOS two are added by dispatching this.
+#
+# NOTE: Gitea exposes workflow_dispatch only for workflows on the DEFAULT branch,
+# so this becomes triggerable once the CI work is merged to `main`.
