fix(conversation): 修复多轮对话历史记录恢复问题并全面优化版本管理

核心修复:
- 修复多轮对话模式下 V2 及以上迭代版本无法正确恢复的 bug
- 修复消息顺序优化后历史记录恢复时，部分消息错误回溯到原始 (V0) 状态的 bug
- 在 iterateMessage 中手动预计算版本号，确保快照中的 appliedVersion 与实际保存的版本号一致
- 重构 useConversationOptimization.ts 中 getMessageAppliedVersion 函数，统一版本语义，使用 record.version 属性而非数组索引进行匹配
- 修正优化快照 (conversationSnapshot) 构建逻辑，确保当前优化消息的 appliedVersion 和 content 始终准确无误
- 改进 conversation optimizer 中的版本匹配机制，使用修剪后的字符串比较防止错误版本不匹配

功能增强:
- 新增完整的 iterateMessage 方法，支持多轮对话的消息级迭代优化
- 传递完整上下文数据（messages、selectedMessageId）给底层服务
- 对比测试时分别维护 originalToolCalls 和 optimizedToolCalls，确保工具调用结果互不干扰
- 在 prompt optimizer 历史元数据中添加 conversationSnapshot 以支持准确的状态恢复
- 重构优化流程，optimizeMessage 现在强制重置状态，避免状态污染

UI 优化:
- 调整版本标签显示顺序为 v3 v2 v1 v0（最新版本在前，v0 固定在最后）
- 优化版本切换交互体验

国际化支持:
- 修复 prompt optimizer 中的硬编码中文字符串，替换为 i18n 键
- 为多轮对话优化添加缺失的 i18n 键

代码质量:
- 删除所有调试日志（console.log）
- 添加模板处理边界情况注释（Mustache 空数组 vs undefined）
- 更新 App.vue (Web 和 Extension) 的历史记录恢复逻辑，通过 record.version 精确查找版本，增强了对历史记录删除（导致版本数组稀疏）的健壮性
- 为对话优化功能暂存未跟踪的新文件

-{{toolsContext}}
-
-Specify: tool names/functions, parameter schema and required params, invocation timing, output structure and post-processing, fallback when tool fails/unavailable. Note:

-- Never fabricate tool outputs; if no tool call occurred, do not produce outputs that imply tool usage

-[No Tools]
-- No tools available. Avoid any tool-specific instructions; if the original prompt assumes tools, convert to a conservative non-tool workflow or propose self-check procedures as substitute.

-
-Optimization Requirements
-- Preserve the core intent and style of originalPrompt; only make minimal sufficient changes driven by context and tool constraints.
-- Output must follow the six sections below (English headings), ensuring completeness, actionability, and verifiability.
-- Output ONLY the optimized system prompt: no extra explanations, no task execution, no user interaction; do not wrap with code fences.

-   - No user interaction, no questions, no explanations, no task execution
-   - No fabrication of external data/tool outputs/sources
-   - No outputs violating declared tool constraints
-3. Edge Handling
-   - Missing context: state conservative assumptions; avoid speculation

-- Step 1: [Primary action under context; specify if/when to call tools]

-As [role title], strictly follow "Rules" and execute per "Workflows". Treat context (if available) as the primary constraint and preserve the core intent of originalPrompt.

+# Optimization Examples
+
+## System Message Optimization
+❌ Weak: "You are an assistant"
+✅ Strong: "You are a professional technical support expert specializing in software troubleshooting. When responding:
+- First diagnose the root cause of the issue
+- Provide clear solution steps
+- Explain the purpose of each step
+- Offer preventive measures and best practices"
+
+**Key Points**: Define role positioning, capability scope, behavioral norms, and output standards

+## User Message Optimization
+❌ Weak: "Help me solve this problem"
+✅ Strong: "My application shows a 'Module not found' error on startup. Environment details:
+- Operating System: Windows 11
+- Node.js Version: 18.16.0
+- Error Message: Cannot find module 'express'
+
+Please help me analyze the cause and provide a solution."
+
+**Key Points**: Clarify requirements, provide background, specify constraints, define expected results
+
+## Assistant Message Optimization
+❌ Weak: "OK, I'll help you with that"
+✅ Strong: "I'll help you analyze this error. Based on the information you provided, this is a dependency issue. I will:
+
+1. First check if express is declared in package.json

+- ✓ Is the expression specific and clear?
+- ✓ Is it coordinated and consistent with the context?
+- ✓ Does it leverage conversation history effectively?
+- ✓ Is the structure and format well-organized?
+- ✓ Is the language clear and fluent?

+# Output Requirements
+
+⚠️ Strict Requirements:
+1. Output the optimized message content directly
+2. Do not add prefixes like "Optimized:"
+3. Do not use code blocks to surround the content
+4. Do not add explanations or comments
+5. Keep the same language as the original message
+6. Do not change the basic intent of the original message`

+**Expected Output Format**:
+1. **Data Overview** (Markdown table)
+   - Revenue, orders, and average order value for each month
+2. **Trend Analysis** (Structured list)
+   - Revenue trend: [Growing/Declining/Stable] + percentage
+   - Order trend: [Growing/Declining/Stable] + percentage
+3. **Anomaly Detection** (if any)
+   - List anomalous months with suspected reasons
+4. **Recommendations** (Numbered list)
+   - At least 3 specific actionable suggestions
+
+**Format Requirements**:
+- Use Markdown formatting
+- Present data in tables
+- Bold trend indicators
+- Use numbered lists for recommendations"

+## 1. Data Overview
+
+| Month | Revenue | Orders | Avg Order Value |
+|-------|---------|--------|-----------------|
+| 2024-01 | $120,000 | 450 | $267 |

+## 2. Trend Analysis
+
+- **Revenue Trend**: Fluctuating growth (+6.7%)
+  - Feb vs Jan: +12.5% increase
+  - Mar vs Feb: -5.2% decrease
+  - Overall: Positive growth
+
+- **Order Trend**: Fluctuating growth (+6.7%)
+  - Feb vs Jan: +15.6% increase
+  - Mar vs Feb: -7.7% decrease
+  - Overall: Positive growth
+
+- **Average Order Value**: Stable ($260-$267)
+
+## 3. Key Insights
+
+1. February was peak month (likely due to Chinese New Year promotions)
+2. March showed decline but still above January baseline
+3. AOV is stable; growth mainly from order volume
+
+## 4. Recommendations
+
+1. **Replicate February Success**: Analyze Feb promotions for future major holidays
+2. **Stabilize AOV**: Launch initiatives to increase average order value (e.g., bundling, minimum purchase discounts)
+3. **Fill Off-Season Gaps**: Design campaigns for months like March
+4. **Data Monitoring**: Establish monthly KPI dashboard to track anomalies in real-time"
+
+**Key Points**: Structured output, data in tables, trends visualized, actionable recommendations

+# Optimization Checklist
+
+After completing optimization, please self-check:
+- ✓ Are formatting elements used (lists/tables/code blocks)?
+- ✓ Are fields and structure clearly defined?
+- ✓ Are concrete format examples provided?
+- ✓ Are validation/acceptance criteria specified?
+- ✓ Is it coordinated and consistent with context?
+- ✓ Is the format readable and parseable?
+
+# Output Requirements
+
+⚠️ Strict Requirements:
+1. Output the optimized message content directly
+2. Do not add prefixes like "Optimized:"
+3. Do not use code blocks to surround the content
+4. Do not add explanations or comments
+5. Keep the same language as the original message
+6. Do not change the basic intent of the original message`
