Closes #7581. After this PR, `describe` shows `(stream)` next to input that arrived at `describe` as a `ListStream`: ```bash 〉ls | describe table<name: string, type: string, size: filesize, modified: date> (stream) 〉[1 2 3] | each {|i| $i} | describe list<int> (stream) ``` `describe` must collect all items of the stream to display type information for lists and tables. If users need to avoid collecting input, they can use the `-n`/`--no-collect` flag: ```bash 〉[1 2 3] | each {|i| $i} | describe --no-collect stream ```
