enricobuehlerandClaude Fable 5 940a260506 fix(host): retry the audio first-open instead of running the session silent
Session start is peak endpoint churn on Windows — the virtual-display
attach and the wiring plan's own IPolicyConfig default flips race the
first WASAPI activate, which then fails transiently (IAudioClient
0x80070002, endpoint mid-re-registration) — and a first-open failure
killed audio for the WHOLE session: wasapi_cap's capture thread sent
the error through the ready handshake and exited, and the native
plane's audio thread returned instead of entering its reopen loop
(each layer's comment claimed the other retried; neither did).

Two-layer fix: the WASAPI capture thread gives the first open three
attempts a second apart before failing the handshake, and the native
audio thread treats a failed first open like a mid-session capture
death — it enters the existing reopen-with-backoff loop, so audio
starts a few seconds late instead of never. The GameStream plane gets
the WASAPI-level retry for free.
