refactor(standalone): split ChatConversation into components
Decompose 1415-line god class into focused components: - ConversationState (shared mutable state) - ConversationEvents (SharedFlow + policy) - ContextBuilder (prefix/memory helpers) - CompactionCoordinator (compaction + LiteConv rebuild) - ToolDispatcher (single tool-call execution) - BackgroundScheduler (review/reflection/mining triggers) - ConversationLoop (orchestrator, implements ProtoConversation) ChatConversation becomes a typealias. Public API preserved.
