docs: register the design and plan in the wiki, with what got rejected

The entity pages carry the rejected alternatives and why, so the next
reader does not have to reconstruct the argument: minimal patch cannot
fill a tier that does not exist, cherry's wire DSL buys four endpoint
protocols we do not have, and default_effort lost its only consumer the
moment enable_thinking=True became Effort.AUTO.
