test: widen QM-follow-up window in info_asking_default test

bdraco · bdraco · commit e3eedbaca481 · 2026-05-20T14:58:39.000-05:00
The 50ms QUICK_REQUEST_TIMEOUT_MS budget for this test left ~35ms of
headroom for the QM query that fires ~11-15ms after the QU; on
macOS-latest skip_cython runs the asyncio short-sleep quantization
occasionally pushed the wake past the 50ms cap, so the loop returned
before the QM was sent and second_outgoing stayed None.

The test only asserts that the second outgoing query is QM, the exact
wall-clock budget is not part of the contract, so bump this test's
timeout to 300ms; that absorbs macOS scheduling jitter without leaning
on the shared QUICK_REQUEST_TIMEOUT_MS constant other tests rely on.
