Code fixes:
- build_oai_resp_metadata accepts status param; completed_at is null
when status is in_progress (was always set to timestamp)
- response.created/in_progress events use zeroed usage (was passing
actual prompt tokens before response was logically started)
- Function call item IDs are now generated once per tool call in
update() and reused consistently across output_item.added,
function_call_arguments.delta, and output_item.done events
(was generating independent random IDs in each path)
- Clean up commented-out status checks in server-common.cpp
Test fixes:
- Assert sequence_number on every event unconditionally (was using
weak "if present" guard)
- Check actual values not just key presence in streaming created
event test (completed_at is None, usage tokens are 0, etc.)
