Please move it to python/library-fuzzers (yes, name is a little misleading). We aren't adding anything to _xxtestfuzz as we are planning to move it all to the repository.

@pablogsal a little ping FYI, since I see you're working on this.

The tokenizer was keeping several versions of the same information and then repairing them when input moved. F- and t-string openings, expressions, and comments now use source spans and a single start location; token columns come from the line pointer, and failures come from the existing status.
The reader now owns its interactive state and pointer relocation, so the old cursor and buffer helpers, source aliases, extra error flag, and multiline location fields are gone. This is the next part of #153569 after #156482.
