Prerequisite for `banger update`'s preflight, which refuses to swap
binaries while anything is in flight. Today's opstate.Registry
exposes Insert/Get/Prune but no iteration; without a snapshot
accessor the update flow can't tell whether a vm.create is
mid-prepare-work-disk.
* opstate.Registry.List(): returns a freshly-allocated snapshot
of every entry. Mutating the slice doesn't poison the
registry. Pinned by tests covering the snapshot semantics
and the empty case.
* api.OperationSummary / OperationsListResult: a public-shape
record per op. Today the Kind is always "vm.create" — the
field exists so future async kinds (image.pull, kernel.pull)
plug in without an API change.
* Daemon.ListOperations + daemon.operations.list RPC:
walks vmService.createOps and emits OperationSummary entries.
Done ops are included in the snapshot; the update preflight
filters by Done itself.
* dispatch_test's documented-methods list updated.
No behaviour change for existing flows; this is a read-only
addition.
