Silent failure in conversation initialization retry logic - max retries exceeded

[jcurlier]

Bug Description

The sendConversationInitWithRetry method fails silently when all retry attempts are exhausted, creating a confusing user experience where the conversation appears to be active but may not work properly.

Current Behavior

When conversation initialization fails after all retries (default: 3 attempts):

1. No error is thrown to the caller
2. State transitions to .active anyway
3. onAgentReady callback fires
4. Conversation may not work properly due to failed initialization

Expected Behavior

When max retries are reached, the method should:

1. Throw an error to indicate failure
2. Prevent state transition to .active
3. Allow proper error handling by the caller
4. Provide clear feedback about the failure
