IsNode's meaning was murky. Add IsBranch, defined as the set of branch
node kinds (home, section, taxonomy, term), and make IsNode a deprecated
alias for it.

When a home page or section page in language A is backed by a file and
language B has no content file for that section, the automatic page for
language B was not replaced by the complement from language A. This
happened because:
1. The content node shifter returned auto pages (not backed by files) as
exact matches without trying complement fallback.
2. findContentNodeForSiteVector immediately returned auto pages as exact
matches without considering file-backed complements.
3. getPagesInSection used Get (no fallback) for IncludeSelf, preventing
complement resolution for home/section pages.
Fix by preferring file-backed complement pages over auto pages in the
shift and lookup mechanisms, and using fallback for self-inclusion.
