alonso.torres 19e5f072b5 🐛 Ask MCP plugins for heartbeats so hidden tabs do not look frozen

The server refuses to send a task to a plugin whose last heartbeat is
older than 30 s, taking its tab for frozen. The plugin sent heartbeats
only from a 10 s timer, and Chrome runs the timers of a hidden page as
rarely as once a minute: without Energy Saver after about a minute
hidden, and at once with it. A Penpot tab hidden for a minute therefore
failed that check about half the time, although it could run tasks.

Chrome handles socket messages of a hidden page at once, and a frozen
page cannot handle them at all. The server now sends each plugin a
heartbeat request every 10 s, and the plugin answers it with a
heartbeat, so the heartbeat age again tells a frozen tab from a hidden
one. The plugin keeps its timer, so it still sends heartbeats to a
server that does not ask. A plugin that does not know the request
passes it to the plugin code, which ignores it.
