Drop all commented-out `TooFastEdit` class,
`reg_err_types`, and `isinstance()` references.
Replace the hard ws-token `assert` in
`subscribe()` with a soft mismatch log that
updates the local `token` ref; cache the result
as `latest_token` for use in sub msgs.
Also,
- Comment out the `reg_err_types` import.
- Switch `pformat` -> `ppfmt` in `openOrders` update log.
