CoGuestStore

Introduction
Co-guest feature enables real-time interaction between hosts and audience members through a seat-based system. CoGuestStore provides a comprehensive set of APIs to manage the entire co-guest lifecycle.
Important: 
Always use the factory method create(liveID:) with a valid live room ID to create a CoGuestStore instance. Do not attempt to initialize directly.
Note: 
Co-guest state updates are delivered through the state publisher. Subscribe to it to receive real-time updates about connected users, invitations and applications.
Warning: 
If a co-guest request does not receive a response within the specified timeout, an event with NoResponseReason.timeout will be triggered. Always handle timeout scenarios in your UI.
Features
Bidirectional Invitation：Hosts can invite audience members, and audience members can also apply to join
State Management：Real-time tracking of connected users, invitations and applications
Event-Driven Architecture：Provides separate event streams for host and guest roles
Timeout Handling：Built-in timeout mechanism for invitations and applications

Guest Operations
applyForSeat
Apply to go on seat
public func applyForSeat(seatIndex: Int = -1, timeout: TimeInterval, extraInfo: String?, completion: CompletionClosure?) { fatalError("\(#function) must be overridden by subclass") }
Request to join co-guest session as an audience member.

After calling this method, a co-guest request is sent to all hosts in the live room. The request will remain active until:
• Host accepts via acceptApplication
• Host rejects via rejectApplication
• Timeout expires
• You cancel via cancelApplication
Version
Supported since version 3.5.
Notes
Note: 
If no host responds within the timeout, {ref2} event with NoResponseReason/timeout will be triggered.
