Previously the initAuth() function set authInitPromise to the async IIFE's
Promise but never cleared it on rejection. The index.ts retry loop called
initAuth() up to 10 times, but on attempt 2+ the check
`if (authInitPromise) { await authInitPromise; return; }` would immediately
re-throw the original rejection without performing a real retry.
Fix: wrap the final `await authInitPromise` in try/catch and reset
authInitPromise = null on error. This allows the index.ts retry loop to
create a fresh attempt on each call after a failure.
