## Version 0.19.0 - XML Tool Format Refactor 🔄 ✅

**Priority:** HIGH
**Status:** Complete (v0.19.0 released)

Рефакторинг: переход на чистый XML формат для tool calls (как в CONCEPT.md).

### Текущая проблема

OllamaClient использует Ollama native tool calling (JSON Schema), а ResponseParser реализует XML парсинг. Это создаёт путаницу и не соответствует CONCEPT.md.

### 0.19.1 - OllamaClient Refactor

```typescript
// src/infrastructure/llm/OllamaClient.ts

// БЫЛО:
// - Передаём tools в Ollama SDK format
// - Извлекаем tool_calls из response.message.tool_calls

// СТАНЕТ:
// - НЕ передаём tools в SDK
// - Tools описаны в system prompt как XML
// - LLM возвращает XML в content
// - Парсим через ResponseParser
```

**Изменения:**
- [x] Удалить `convertTools()` метод
- [x] Удалить `extractToolCalls()` метод
- [x] Убрать передачу `tools` в `client.chat()`
- [x] Возвращать только `content` без `toolCalls`

### 0.19.2 - System Prompt Update

```typescript
// src/infrastructure/llm/prompts.ts

// Добавить в SYSTEM_PROMPT полное описание XML формата:

const TOOL_FORMAT_INSTRUCTIONS = `
## Tool Calling Format

When you need to use a tool, format your call as XML:

<tool_call name="tool_name">
  <param_name>value</param_name>
  <another_param>value</another_param>
</tool_call>

Examples:
<tool_call name="get_lines">
  <path>src/index.ts</path>
  <start>1</start>
  <end>50</end>
</tool_call>

<tool_call name="edit_lines">
  <path>src/utils.ts</path>
  <start>10</start>
  <end>15</end>
  <content>const newCode = "hello";</content>
</tool_call>

You can use multiple tool calls in one response.
Always wait for tool results before making conclusions.
`
```

**Изменения:**
- [x] Добавить `TOOL_FORMAT_INSTRUCTIONS` в prompts.ts
- [x] Включить в `SYSTEM_PROMPT`
- [x] Добавить примеры для всех 18 tools

### 0.19.3 - HandleMessage Simplification

```typescript
// src/application/use-cases/HandleMessage.ts

// БЫЛО:
// const response = await this.llm.chat(messages)
// const parsed = parseToolCalls(response.content)

// СТАНЕТ:
// const response = await this.llm.chat(messages)  // без tools
// const parsed = parseToolCalls(response.content) // единственный источник
```

**Изменения:**
- [x] Убрать передачу tool definitions в `llm.chat()`
- [x] ResponseParser — единственный источник tool calls
- [x] Упростить логику обработки

### 0.19.4 - ILLMClient Interface Update

```typescript
// src/domain/services/ILLMClient.ts

// БЫЛО:
interface ILLMClient {
    chat(messages: ChatMessage[], tools?: ToolDef[]): Promise<LLMResponse>
}

// СТАНЕТ:
interface ILLMClient {
    chat(messages: ChatMessage[]): Promise<LLMResponse>
    // tools больше не передаются - они в system prompt
}
```

**Изменения:**
- [x] Убрать `tools` параметр из `chat()`
- [x] Убрать `toolCalls` из `LLMResponse` (парсятся из content)
- [x] Обновить все реализации

### 0.19.5 - ResponseParser Enhancements

```typescript
// src/infrastructure/llm/ResponseParser.ts

// Улучшения:
// - Лучшая обработка ошибок парсинга
// - Поддержка CDATA для многострочного content
// - Валидация имён tools
```

**Изменения:**
- [x] Добавить поддержку `<![CDATA[...]]>` для content
- [x] Валидация: tool name должен быть из известного списка
- [x] Улучшить сообщения об ошибках парсинга

**Tests:**
- [x] Обновить тесты OllamaClient
- [x] Обновить тесты HandleMessage
- [x] Добавить тесты ResponseParser для edge cases
- [ ] E2E тест полного flow с XML (опционально, может быть в 0.20.0)
