docs: what is postponed or rejected stays in its own two files

Docs and comments outside future-work.md and review-rejections.md say what the code
does, and point nowhere else for what it doesn't: the architecture page's map, the
transports' forwarders, keys with `/`, a strict swarm's registry, trust.md's "Not yet"
(now saying what isn't protected, in a sentence), the topology bench, and the comments
of the change benchmarks, capabilities' grantor, tokens, dissemination, refusals and
topology.
