the previous script uses an outdated API and is not functional. I offer my working script with API v2

This replaces a convention-compliant implementation with a script that breaks several hard rules, so it can't be accepted in this form:

1. It redefines _debug(), overriding acme.sh's core function for the whole run.
2. Raw curl — must use _get/_post. echo >&2 — must use _err/_info.
3. Record id persisted to /tmp/timeweb_*.id — don't store state; look the record up from the API in rm by name + value.
4. Generic helper names (_load_token, _add_txt_record) — prefix with _timeweb_.
5. TW_Token must be loaded/saved via _readaccountconf_mutable/_saveaccountconf_mutable; comments must be English; shfmt is failing.
6. The DNS-API-Test must pass in your fork.

If v1 is really dead (please link an announcement), the right move is to update the existing implementation's endpoints to v2, keeping its structure — not replace the file.
