Flip the depot Registry entry to Wired: true with its command list
(status/push/verify/get/pull), so crucible depot/depot status/etc.
route to depot.Run instead of the fail-closed unwired path. Update
dispatch_test.go: the canonical command surface, command-metadata
completeness (depot has no AppCommand since it parses its own
subcommands), the menu-items test (depot now expected in the menu),
and a new test asserting depot's stderr never reaches the dispatcher's
"not wired yet" message. Drop the stale "(SeaweedFS)" summary wording.
