fix(skills): inject skill list into system prompt for LLM awareness

Problem: Agent could not invoke appropriate skills when user asked about
financial reports because LLM didn't know which skills were available.

Root causes:
1. System prompt lacked available skill list
2. SkillManifest struct missing 'triggers' field
3. SKILL.md loader not parsing triggers list
4. "财报" keyword not matching "财务报告" trigger

Changes:
- Add triggers field to SkillManifest struct
- Parse triggers list from SKILL.md frontmatter
- Inject skill list into system prompt in kernel.rs
- Add "财报", "财务数据", "盈利", "营收" triggers to finance-tracker
- Add "财报分析" trigger to analytics-reporter
- Document fix in troubleshooting.md

## 9.4 自我进化系统启动错误
### 问题DateTime 类型不匹配导致编译失败
**症状**:
```
error[E0277]: cannot subtract `chrono::DateTime<FixedOffset>` from `chrono::DateTime<Utc>`
--> desktop\src-tauri\src\intelligence\heartbeat.rs:542:27
|
542 | let idle_hours = (now - last_time).num_hours();
| ^ no implementation for `chrono::DateTime<Utc> - chrono::DateTime<FixedOffset>`
```
**根本原因**: `chrono::DateTime::parse_from_rfc3339()` 返回 `DateTime<FixedOffset>`,但 `chrono::Utc::now()` 返回 `DateTime<Utc>`,两种类型不能直接相减。
**解决方案**:
将 `DateTime<FixedOffset>` 转换为 `DateTime<Utc>` 后再计算:
```rust
// 错误写法
let last_time = chrono::DateTime::parse_from_rfc3339(&last_interaction).ok()?;
let now = chrono::Utc::now();
let idle_hours = (now - last_time).num_hours(); // 编译错误!
// 正确写法
let last_time = chrono::DateTime::parse_from_rfc3339(&last_interaction)
.ok()?
.with_timezone(&chrono::Utc); // 转换为 UTC
let now = chrono::Utc::now();
let idle_hours = (now - last_time).num_hours(); // OK
```
**相关文件**:
- `desktop/src-tauri/src/intelligence/heartbeat.rs`
### 问题:未使用的导入警告
**症状**:
```
warning: unused import: `Manager`
warning: unused import: `futures::StreamExt`
```
**解决方案**:
1. 手动移除未使用的导入
2. 或使用 `cargo fix --lib -p <package> --allow-dirty` 自动修复
**自动修复命令**:
```bash
cargo fix --lib -p desktop --allow-dirty
cargo fix --lib -p zclaw-hands --allow-dirty
cargo fix --lib -p zclaw-runtime --allow-dirty
cargo fix --lib -p zclaw-kernel --allow-dirty
cargo fix --lib -p zclaw-protocols --allow-dirty
```
**注意**: `dead_code` 警告(未使用的字段、方法)不影响编译,可以保留供将来使用。

## 10. 技能系统问题
### 10.1 Agent 无法调用合适的技能
**症状**: 用户发送消息(如"查询某公司财报"Agent 没有调用相关技能,只是直接回复文本
**根本原因**:
1. **系统提示词缺少技能列表**: LLM 不知道有哪些技能可用
2. **SkillManifest 缺少 triggers 字段**: 触发词无法传递给 LLM
3. **技能触发词覆盖不足**: "财报" 无法匹配 "财务报告"
**问题分析**:
Agent 调用技能的完整链路:
```
用户消息 → LLM → 选择 execute_skill 工具 → 传入 skill_id → 执行技能
```
如果 LLM 不知道有哪些 skill_id 可用,就无法主动调用。
**修复方案**:
1. **在系统提示词中注入技能列表** (`kernel.rs`):
```rust
/// Build a system prompt with skill information injected
fn build_system_prompt_with_skills(&self, base_prompt: Option<&String>) -> String {
let skills = futures::executor::block_on(self.skills.list());
let mut prompt = base_prompt
.map(|p| p.clone())
.unwrap_or_else(|| "You are a helpful AI assistant.".to_string());
if !skills.is_empty() {
prompt.push_str("\n\n## Available Skills\n\n");
prompt.push_str("Use the `execute_skill` tool with the skill_id to invoke them:\n\n");
for skill in skills {
prompt.push_str(&format!(
"- **{}**: {}",
skill.id.as_str(),
skill.description
));
if !skill.triggers.is_empty() {
prompt.push_str(&format!(
" (Triggers: {})",
skill.triggers.join(", ")
));
}
prompt.push('\n');
}
}
prompt
}
```
2. **添加 triggers 字段到 SkillManifest** (`skill.rs`):
```rust
pub struct SkillManifest {
// ... existing fields
/// Trigger words for skill activation
#[serde(default)]
pub triggers: Vec<String>,
}
```
3. **解析 SKILL.md 中的 triggers** (`loader.rs`):
```rust
// Parse triggers list in frontmatter
if in_triggers_list && line.starts_with("- ") {
triggers.push(line[2..].trim().trim_matches('"').to_string());
continue;
}
```
4. **添加常见触发词** (`skills/finance-tracker/SKILL.md`):
```yaml
triggers:
- "财务分析"
- "财报" # 新增
- "财务数据" # 新增
- "盈利"
- "营收"
- "利润"
```
**影响范围**:
- `crates/zclaw-kernel/src/kernel.rs` - 系统提示词构建
- `crates/zclaw-skills/src/skill.rs` - SkillManifest 结构
- `crates/zclaw-skills/src/loader.rs` - SKILL.md 解析
- `skills/*/SKILL.md` - 技能定义文件
**验证修复**:
1. 重启应用
2. 发送"查询腾讯财报"
3. Agent 应该调用 `execute_skill` 工具,传入 `skill_id: "finance-tracker"`
