Cabeza 6879090caa fix(google_genai): retry a stream that drops before its first event
The async generateContent handler returned its streaming iterator as soon as
the response headers arrived, so the first body read happened in the proxy's
data generator, long after the router had recorded the call as a success and
spent its retry budget. A stream that dropped before its first event therefore
reached the client as an in-stream error frame with attempted_retries unset,
and router_settings.num_retries never applied.

Read the first SSE event inside the handler instead, so a drop raises where the
router's retry loop can see it and is mapped to a retriable status. Gemini
sends no lifecycle frames before content, so one event proves the stream is
alive, and the event is replayed to the consumer unchanged. A stream that ends
before its first event stays a valid empty answer and ends the iterator with
its logging intact.

The abandoned response is closed when priming fails, so a dropped stream does
not hold a pooled connection while the retry runs.

The synchronous path has the same shape but is out of scope here: it has no
caller that returns before the first read.

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
