Serialises (re)compilation of the per-event plugin modules.

Compile requests are queued and run one at a time so the dynamically generated event modules are never created and destroyed concurrently.

The compiled module is per node (in-memory, not in Mnesia). On boot each node builds its own copy from the replicated table; at runtime a local (re)compile is broadcast cluster-wide so every node rebuilds the affected event from the replicated table — keeping Hook.call/3 consistent across the cluster.

Telemetry

• [:mishka_installer, :event, :compile] — emitted after an event module is (re)built. Metadata: :event, :result (:ok | :error).
• [:mishka_installer, :event, :synchronized] — emitted once all events have started after the Mnesia store is ready. Metadata: :node.
