Contract

• assert console.print(end="") with no objects emits an empty string instead of an unwanted newline
• assert console.print(end="prefix ") with no objects emits the custom end string
• assert console.print() with no arguments still emits a default newline
• assert Text.from_ansi preserves trailing newlines instead of stripping them via splitlines
• assert Text.from_ansi on a bare newline returns text with length 1 containing newline
• assert FileProxy.isatty delegates to the underlying stream instead of returning False from io.TextIOBase
