fix(share): не утекать errorText тулов и провайдера анониму в публичном шэре (closes #394)
SECURITY. В публичном share-чате сырой текст ошибки тула или провайдера утекал анонимному читателю. Три слоя, все обязательны: (1) Рендер-гейт: prop showErrors в ToolCallCard (протянут через MessageList/ MessageItem), share-виджет передаёт false — сырой errorText не рисуется. Но рендер-гейт маскирует только DOM, не байты. (2) Санитизация на уровне share-тулсета (авторитетно): forShare оборачивает execute каждого тула catch'ем. Своя ShareToolError (безопасные строки: «page not available in this share») пробрасывается, ЛЮБАЯ другая ошибка → generic «tool could not complete», полный текст только в серверный лог. Одно место закрывает байты (атомарный tool-output-error фрейм v6), рендер и контекст модели; self- correction сохранена. (3) Анонимный onError пайпа: ShareToolError → её безопасное сообщение; иначе describeProviderError (statusCode + тело: внутренний baseUrl/модель) только в лог, читателю — фиксированная классифицированная строка (rate-limited/unavailable/ provider error). Тест: интеграционный с РЕАЛЬНЫМ падением тула и провайдера — assert по СЫРЫМ SSE- БАЙТАМ (не по DOM): секрет/baseUrl/стек отсутствуют, видна безопасная строка, полный текст провайдера ушёл в серверный лог.
