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).

# THROWAWAY build smoke-test for the macOS (Tart) runner. Verifies both
# *-apple-darwin targets actually compile and link (incl. arboard's AppKit)
# through the flake on the real Mac, before the full release-macos workflow is
# wired. Delete once that lands.
#
# Push-triggered (workflow_dispatch only works for workflows on the default
# branch; our CI is on `ci`). Runs when the flake/toolchain or this file change.
# Bring the Mac up before pushing so the run isn't left queued.

# 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`.
