重构: CR-11 composables+ToolCard 健壮性 6 子项

⑦ useAiConversations JSON.parse 逐条 try/catch 容错(坏条降级不清空整对话);⑧ ToolCard 去 as any + argString 安全取字段;⑨ useAiSend approveToolCall 复用 findToolCall;⑩ useAiEvents 补 AiHeartbeat case 防穿透;⑪ approveHumanApproval 签名收敛(decisions:string[] + select_type 判单/多选)+ ProjectDetail 调用方同步(单选包数组/多选直传);⑫ ToolCard formatBytes/formatToolName/argString 兜底。批5 ww1mh6mry,vue-tsc 0
