Documents the event-loop watchdog from duneorg/dune#51 (tracking issue duneorg/dune#42): what it does on a stall, the limits and env vars, when it holds fire (suspended processes, debuggers), watchdogProgress() / watchdogGrace() for legitimately synchronous work, restarting after a kill (systemd example with StartLimitBurst; dune dev deliberately doesn't restart), what happens to child processes, adding .dune/ to .gitignore (hang reports land there), and adding .dune/ to .gitignore (hang reports land there), and what to check if it hangs anyway.

Describes behavior from duneorg/dune#51, so merge with or after it; the dune docs submodule pointer then needs a bump. New page: 05.deployment/10.hang-watchdog.
