Treat all whitespace as slash-command terminator

The slash parser only checks afterCursor.includes(' '), so it ignores other whitespace like \n or tabs. In a multiline draft such as /st\nnext, placing the caret before the newline keeps slash mode active because afterCursor has no literal space, which can reopen the popup and route Enter to command selection instead of normal send/edit behavior. This should use a whitespace check (e.g. /\s/) consistent with the rest of the parser.

Let's do something about those extra-long helper strings but otherwise looks OK to me.
