Add sfw aggregator gate to enforce required CI checks (#89)

* ci: add Socket Firewall aggregator gate; bump 3.2.0 -> 3.2.1

Add a single sfw-gate job (if: always(), needs the conditional inspect +
free/enterprise smoke + workflow-notice jobs) that fails only when an
upstream job failed or was cancelled -- success and skipped both pass.

This is the check intended to become the required status check on main:
the smoke jobs are conditional (deps-changed gates them, and exactly one
of free/enterprise runs per PR), so none can be required directly -- a
required check whose job is if-skipped is never created and blocks merge
forever. The gate is green when no deps change and is satisfied by
whichever smoke path actually ran.

NOT yet wired into branch protection -- added during a soak period so the
check is visible before it becomes blocking, and so requiring it doesn't
strand other open PRs.

Pattern adapted from SocketDev/socket-python-cli #224.

* ci: spell out 'iff' as 'if and only if' in gate comment

Review feedback: 'iff' read as a typo. It is the logic shorthand for
'if and only if', but the comment exists to communicate, so spell it out.
