docs(runtime-logs): implement runtime log management features

Добавлены новые возможности для работы с файловыми логами Docker-сервисов:
- Эндпоинты для получения списка логов и хвоста лог-файла.
- Очистка лог-файлов с возможностью выбора режима (truncate или delete) и запись в аудит очистки.
- Обновлена документация и конфигурация для поддержки новых функций.

 После `deploy_apply` CP шлёт `POST https://AGENT_DOMAIN/v1/agent/sync` с `Authorization: Bearer <agent_secret>`. На реплике — `EVOBGP_AGENT_SECRET`, Traefik `PANEL_IP_WHITELIST`. Подробнее: [remote-speakers.md](remote-speakers.md).
 
+## Runtime log-файлы (`EVOBGP_RUNTIME_LOGS_DIR`)
+
+Файловые логи Docker-сервисов (sidecar `stack-runtime-logs` в compose) читаются API **только** в процессе **`evobgp-all`**, когда заданы обе переменные:
+
+```text
+EVOBGP_SERVICE=evobgp-all
+EVOBGP_RUNTIME_LOGS_DIR=/opt/evobgp/runtime-logs
+```
+
+В dev-профиле compose каталог на хосте обычно `./runtime-logs`, в контейнере — mount на `/opt/evobgp/runtime-logs`. Если каталог не задан или роль процесса не `evobgp-all`, эндпоинты `/v1/runtime-logs/*` отвечают **503** (`runtime_logs_unavailable`). Очистка файлов — роль **operator+**; операции пишутся в таблицу `runtime_log_cleanup_audit`.

 ## Текущий фокус
 
 **Task:** `settings-ui-and-runtime-logs`  
-**Complexity:** Level 4  
+**Phase:** **BUILD Phase 2 complete** → **Phase 3** (HTTP handlers)
-**Phase:** **CREATIVE complete** → **`/build`**
 
-## Creative decisions (кратко)
+## Phase 2 deliverables
 
-| CP | Решение |
+- `internal/runtimelogs/` — Config, Service, safe path, List/Tail/Cleanup
-|----|---------|
+- `EVOBGP_RUNTIME_LOGS_DIR` в `internal/config/config.go`
-| CP-1 | `/tenant-settings` + Tabs; mainNav «Параметры»; `/settings` = frontend |
+- `docs/access.md` — документация env
-| CP-2 | Monitoring tab `runtime-logs`; sub-tabs `files` / `audit` |
-| CP-3 | Cleanup default `truncate`; max 512 MiB; tail 200 lines (max 2000), 256 KiB cap |
-| CP-4 | Regex `^[a-z0-9][a-z0-9_.-]*\.log$` + EvalSymlinks + root prefix |
 
-## Коммиты creative (local, no push)
+## Ключевые константы
 
-1. `ceb6f2f` — CP-1 tenant settings UI  
+- Guard: `EVOBGP_SERVICE=evobgp-all` + non-empty absolute `EVOBGP_RUNTIME_LOGS_DIR`
-2. `e27936c` — CP-2 runtime logs UI  
+- Cleanup max: 512 MiB; tail: 200 default, 2000 max, 256 KiB read cap
-3. `493575a` — CP-3 cleanup & tail  
+
-4. (pending) — CP-4 path safety  
+## Тесты
+
+- `go test ./internal/runtimelogs/...` — pass
+- `scripts/lint-go.ps1` — pass
 
 ## Следующий шаг
 
 ```
-/build Phase 1
+/build Phase 3
 ```
 
-OpenAPI + migration `000026` + store (см. `tasks.md`).
+HTTP handlers + routes для `/v1/runtime-logs/*`.
