- errors.py: always emit the stdlib log line with full exception detail;
  record_error/record_event never raise and silently no-op on a disabled
  runtime, so the previous except-fallback was dead code and a correlation
  id could point at nothing server-side.
- logfire_legacy.py: track whether configure_logfire actually ran with a
  token and expose logfire_is_configured(); logfire's own send_to_logfire
  flag defaults to True on an unconfigured instance, so auth.py's
  audit-event gate and errors.py's legacy export gate never worked.
- endpoints.py: stop recording 500/404 request errors on the budget-window
  poll degraded path, which returns a successful 202 seed response; emit a
  degradation event plus stdlib warning instead of false
  http_request_failed events and mislabeled error metrics.
- observability.py + modal/app.py: worker operations now carry the Modal
  identity attributes (platform, runtime_role, modal_environment,
  modal_app_name, modal_function_name) via process_static_attributes();
  plain-process runtimes have no FastAPI-adapter injection point, so the
  attributes never reached worker operation logs.
- budget_window_scheduler.py: replace per-iteration child-poll and
  backoff-sleep segments with bounded aggregate attributes; each segment
  appends a node to the operation's in-memory segment tree, so a
  near-timeout batch grew memory without bound and emitted an operation
  log line large enough to be truncated.

Modal's Function.from_name / Dict.from_name / FunctionCall.from_id return
lazy handles: constructing them only runs a local name check, and the
control-plane RPC fires on first use. The MODAL_DICT_READ and
MODAL_FUNCTION_LOOKUP segments therefore measured ~0ms while the real
network cost ran unattributed.

- list_versions / get_country_versions: move the dict(...) iterations —
  where hydration and the DictContents/DictGet RPCs happen — inside the
  MODAL_DICT_READ segments.
- submit endpoints: fold the lazy Function.from_name into the
  MODAL_FUNCTION_SPAWN segment, which is where its hydration RPC actually
  executes, and drop the MODAL_FUNCTION_LOOKUP segment name.
- budget window scheduler: drop the lookup segment around the lazy child
  Function handle; BUDGET_WINDOW_CHILD_SPAWN already times the spawn.
