Refactor engines that parse ISO 8601 dates with strptime to use
fromisoformat instead. In most cases this is a direct replacement of
strptime(text, "format") with fromisoformat(text).
For engines where the source has a trailing "Z" that strptime consumed
as a literal (e.g. "%Y-%m-%dT%H:%M:%S.%fZ" in huggingface.py), add
rstrip("Z") to keep the output naive and preserve the existing behavior.
In sogou.py the date is extracted with a regular expression, which can
yield strings like "2026-7-11". strptime accepts this via its format
string, but fromisoformat does not. To preserve the existing behavior
and satisfy the format fromisoformat expects, add zero-padding for the
month and day.

The requests changed here all run outside of the network context timeout,
thereby preventing the engine's timeout from being applied (the engine's timeout
can become longer than it was configured).

These engines override the user agent manually using `gen_useragent`, although that's already done in the online preprocessor that runs before the actual `request(query, params)` method is called. Hence, this call is duplicated.

Fixes the semantic scholar engine by extracting a ui version token.
BTW: remove html tags from the content.
Author's checklist:
- they are ratelimiting very fast, if you do approx more than 2 requests per
minute, you have to wait some time again...
- they also have an official api at api.semanticscholar.org, but it's ratelimits
are even harder
