Interrupted runs now return to the queue instead of failing - an app
shutdown is not a model error and must not spend the task's bounded
retry budget. Startup work moves behind the single-instance lock so a
losing second instance can never run recovery against the live
instance's database. Background provider requests that died before
receiving an external response id now fail at boot (the background
worker can only resume accepted ones). Agent updates resolve the
department through the same canonical lookup as hires, replacing the
free-text write and its invented "General" default.
A task_run still marked running at startup has no executor - the
single-instance app that owned it is gone - yet nothing failed it, the
queue worker only claims queued rows, and the heartbeat excludes tasks
with a running run, so one interrupted shutdown wedged the company
forever. Boot now fails orphaned running runs and their in-flight
foreground provider requests (auditably), which hands the task back to
the heartbeat for an automatic retry. Background provider requests are
untouched; the background worker resumes those by external id.
