Subject: [PATCH] fix(tools): use boolean error flag in web_fetch and
 web_search error responses

Return error: true (boolean) with code field instead of error: "string_code"
to match ToolErrorPayload convention. Also update runner.ts formatRunLogToolSummary
to prefer details.code for error categorization.
