refactor: break up lifespan() into focused helpers

Extract _init_services(), _auto_prune(), _register_error_recorder(),
and _shutdown() from the 142-line lifespan() context manager, reducing
it to ~25 lines that read as a clear startup/shutdown sequence.

Fixes #514

+  The `epoch` field carries the symbolic notation.
+
 SUCCESS DEFINITION:
   A cycle is only "success" if BOTH conditions are met:
     1. The hermes process exited cleanly (exit code 0)
     2. Main is green (smoke test passes on main after merge)
-

   A cycle that merges a PR but leaves main red is a FAILURE.
   The --main-green flag records the smoke test result.
