Consolidate: 65 decision records to 23

Every remaining cluster merged. Each was one design that had been split across
several records because it was worked out over days rather than at once.

Nothing was dropped. Each consolidated record carries the reasoning of the ones
it absorbs -- the measurements, the incidents, the alternatives rejected --
because that reasoning is the only reason to keep a record at all. What is gone
is the fragmentation: eight files to read to understand tier 0, when tier 0 is
one component.

The four superseded records went too. They existed to point at their
successors, and the successors now contain what they said.

The checker made this safe. Each merge left dangling links -- 38 files after
the host merge alone -- and it named every one. Nothing was found by reading,
and a manual pass would certainly have missed some, including references inside
AGENTS.md which every session loads.
