Temporary diagnostic for the class of bug story 83ff386d47c6 hit
2026-05-23: POST /generation/start returned 202, then total silence
— no log, no DB state update, py-spy showed event loop idle with no
GenerationRunner frame anywhere. Strongly suggests a created_task()
result not held → GC'd → silent destroy.
PYTHONASYNCIODEBUG=1 emits "Task was destroyed but it is pending"
and "Task exception was never retrieved" warnings to stderr; that
should distinguish lost-task from cancelled-task on the next attempt.
Per skaldsong-dev's note, remove once they wire proper task-exception
capture upstream.
