Runs mix hex.audit or mix deps.audit across the root, mailglass_admin,
and mailglass_inbound Mix projects, filtering findings through the shared
Mailglass.SupplyChain.AcceptedAdvisories allowlist.
Usage
mix mailglass.audit --kind hex
mix mailglass.audit --kind deps--kind hex also evaluates the allowlist's own health: an accepted entry
whose recheck_by date has passed, or that matched no current finding
across all three directories, blocks delivery even when every live finding
is otherwise accepted (D-10, VULN-06). --kind deps applies alias-aware
suppression only — it does not independently re-litigate entry health,
because mix deps.audit does not natively detect these two entries (see
Mailglass.SupplyChain.AcceptedAdvisories's "Known limitation" moduledoc
section).
