* test: drop the cwd-relative sys.path.insert calls from the test suite
TQ003 stands at 1,077 across 1,058 files, and 1,015 of them are the same shape:
sys.path.insert(0, os.path.abspath("../..")) and its deeper siblings. The
argument resolves against the working directory rather than the file, so from
the repo root, where every job runs pytest, it inserts the directory two levels
above the checkout. It has never pointed at litellm. The package is installed
into the environment anyway, which is what actually makes the import work, and
what the rule's message has said all along.
Removing them leaves 1,634 imports of sys and os with no remaining reference,
and those go too, except where another test module imports the name back out of
the file. The rest of TQ003 is 62 call sites that resolve against __file__ or a
variable, which are a different question and are left alone.
Collection is identical either way: 45,871 tests and the same 51 pre-existing
collection errors before and after, and ruff reports no new undefined name.
* test: drop the duplicate imports the sys.path sweep exposed to F811
* test(pre-call-utils): restore the os import the new bedrock tests need
Codecov flagged the ModelResponse-branch lines as uncovered: add async
per-token normalization, plus zero-completion-token fallback tests for
both handlers (the else branch storing plain float seconds).

log_success_event/async_log_success_event only converted the
end_time - start_time timedelta to float seconds inside the
isinstance(response_obj, ModelResponse) branch, so every embedding /
speech / image response appended a raw timedelta to the latency list
and broke the Redis cache sync with 'Object of type timedelta is not
JSON serializable' (no cross-replica latency sharing for those model
groups + error-log spam). Normalize response_ms to float seconds
up-front in both handlers.
Completes the partial fix from #14040. Fixes#33169
