Subject: [PATCH] Checkpoint: Full Development Complete: All 4 Phases
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Phase 1 (Fixed): Agent Management UI
- Исправлена авторизация: agents переведены на publicProcedure
- AgentDetailModal: 5 вкладок (General, LLM Params, Tools, History, Stats)
- Полное редактирование: model, provider, temperature, topP, maxTokens, frequencyPenalty, presencePenalty, systemPrompt
- Управление allowedTools и allowedDomains через теги
- AgentCreateModal: создание агентов с выбором модели из Ollama API
- Кнопка Metrics на каждой карточке агента

## Phase 2+3: Tool Binding System
- server/tools.ts: реестр из 10 инструментов (http_get, http_post, shell_exec, file_read, file_write, docker_list, docker_exec, docker_logs, browser_navigate, browser_screenshot)
- Безопасное выполнение: проверка allowedTools агента, accessControl из БД
- tools.execute tRPC endpoint
- Tools.tsx: страница управления инструментами с тест-выполнением
- Добавлен пункт "Инструменты" в sidebar навигацию

## Phase 4: Metrics & History
- AgentMetrics.tsx: детальная страница метрик по агенту
- Request Timeline: bar chart по часам (success/error)
- Conversation Log: история диалогов с пагинацией
- Raw Metrics Table: все метрики с токенами и временем
- Time range selector: 6h/24h/48h/7d
- Маршрут /agents/:id/metrics

## Tests: 24/24 passed
- server/auth.logout.test.ts (1)
- server/agents.test.ts (7)
- server/tools.test.ts (13)
- server/ollama.test.ts (3)
