Splits comments into general and inline buckets, oldest first. The
unresolved filter applies only to inline threads — general comments are
not resolvable in the Bitbucket API and are always kept.
Marks a comment thread as resolved. Bitbucket resolves the whole thread, so
comment is the id of its root — the entry bb pr view reports without a
parent. The response body carries only the resolution, which adds nothing
the caller does not already know, so it is discarded.
