almanac: tighten topics graph, remove redundant parents and thin single-page topics

Drop the `manuals` and `release` topics: each duplicated the membership
of an existing topic (`runtime-resources`, `product`) with no added
retrieval value. Fix redundant `architecture` parent edges on
`automation` and `safety`, which already reach `architecture` through
`lifecycle`/`setup`; `automation` also gains `setup` as a direct parent
since its two tagged pages already live in that neighborhood.
