Changed from single 2-second delay to 5 attempts at 500ms intervals.
This provides faster detection while covering a longer window (2.5 seconds total).
The polling loop:
- Checks every 500ms for up to 5 times
- Stops immediately if keygen is already triggered
- Stops if session context changes (user cancelled/navigated away)
This handles the case where the last joiner triggers session_started
but cannot receive the event themselves.
