Mirrors gen_registry's to_list/1: every (key, subject) pair via a direct ets:tab2list read — no gen_server round-trip, same staleness caveat as lookup. Lets callers sweep the registry (rebalancing, metrics, draining) without maintaining a parallel key index. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

to_list/1: returns every(key, subject)pair via a directets:tab2listread — no gen_server round-trip, same staleness caveat aslookup(a just-died process may linger one row until the EXIT is processed). The table isprotected, so cross-process reads are already part of the access model.reduce/3parity falls out asto_list |> list.fold;count/sampleleft out until needed.Motivation: otters/dance's cluster rebalancer currently maintains a parallel index of started keys purely because reki couldn't be iterated. With this, that bookkeeping gets deleted.
Includes tests (round-trip + dead-entry pruning) and a version bump to 1.2.0.
