Google Drive library sync failed on Android: after the first few requests
every files.list threw `error sending request for url (...)` and the sync
stuck at "Syncing 0 / N". The provider's backoff only retried 429/5xx
responses; a thrown fetch propagated immediately. On mobile a long
multi-request sync hits transient transport failures (a pooled keep-alive
connection to googleapis.com going bad), so without a retry every request
after the first batch failed.
- withBackoff now retries a thrown fetch with the same bounded exponential
backoff as 429/5xx, letting reqwest re-establish a fresh connection.
- mapDriveError classifies a thrown transport error (TypeError, or the
Tauri HTTP plugin's plain "error sending request" Error) as NETWORK
instead of UNKNOWN, so the engine's head-probe short-circuit treats it
as transient.
