Use the same logic for marking ranges in the document, and ensure
that the heading range does not include section edit links or
section numberings.

We avoided fixing these because it causes changes in just about all of
the test data, which is annoying when reviewing or blaming changes.
But the previous several commits also caused changes in just about all
of the test data, so we might as well do this too.

To avoid old threads re-appearing on popular pages when someone
uses a vague title (e.g. dozens of threads titled "question" on
[[Wikipedia:Help desk]]: https://w.wiki/fbN), include the oldest
timestamp in the thread (i.e. date the thread was started) in the
heading ID.

Sequential numbers aren't great because they change when an earlier
comment is archived. Parent comment/heading IDs should change less
often.
This also makes much more sense for disambiguating subsections,
e.g. a dozen identical ===Votes=== sections for a dozen proposals.

Our threads now also contain all replies to their sub-threads.
This is similar to how sections work in MediaWiki, where the parent
section also contains the content of all the lower-level sections.
We're going to need this for notifications about replies in a thread.

Previously, only comments could have IDs, because we only needed IDs
for replying. But we might also use them for notifications soon.
