Message:

Posts, Post Types: Allow boundary post lookups outside single posts.

Allow get_boundary_post() to return the first or last post on non-singular pages. Retain the missing-post guard when $in_same_term needs a current post, and continue rejecting unknown taxonomies.

Add coverage for non-singular lookups and the missing-post case.
