fix: cherry-pick PR#94 improvements + dashboard loading fix

- ws-client: connection dedup (_connecting state), connect() guard, global singleton
- chat: 8 null guards (sendMessage/doSend/createStreamBubble/renderAttachments/showPageGuide/loadHistory)
- chat: auto-scroll control (wheel/touch/scrollBtn, disable on scroll-up)
- chat: tool call rendering (appendToolsToEl, collectToolsFromMessage, upsertTool, mergeToolEventData)
- chat: tool event tracking (agent tool events -> _toolEventData/_toolRunIndex)
- chat: extractChatContent/extractContent/dedupeHistory full tools support
- chat.css: .msg-tool collapsible card styles
- dashboard: .catch() on loadDashboardData fire-and-forget, error state + retry button
