Research direction

Start by reading the existing StripStream behavior and the requested SanitizeStream mode described here. Establish which formatting sequences remain allowed and which dangerous actions, such as terminal-title changes, must be removed; done means preserving color and similar text formatting while stripping those actions.

Written by the indexing model from the issue text.

Description

anstream currently has two modes: Printing all ANSI sequences, and stripping all ANSI sequences (StripStream). Would it be possible to add a third mode SanitizeStream, that allows color and similar text formatting streams, but strips potentially dangerous actions such as setting the terminal title?

This request is due to https://github.com/tokio-rs/tracing/issues/3378, where tracing now allows either escaping ANSI (not stripping, leading to bad output with strange characters), or turning off this validation completely. Does this fit in the scope of anstyle?
