Discover new outbound ChatService conversations

Arm a bounded discovery confirmation when the first direct IM is sent to a resident absent from the validated conversation list. Preserve the existing priority placeholder across the first validated miss, then retry the shared list path after the manager-wide delay.

Leave listed conversations and inbound priority behavior unchanged, and retire the unresolved candidate after a second miss so no general live-message debounce or parallel scheduler is introduced.

Validated with the RelWithDebInfo secondlife-bin build and the LLChatServiceHistoryCore test suite.
