feat(macp): add registerMacpCommand for mosaic macp CLI surface

Adds mosaic macp tasks list|submit|gate|events tail subcommands to
@mosaicstack/macp, wires registerMacpCommand into the root mosaic CLI,
and ships a smoke test asserting command structure without touching disk
or starting an event emitter. Ref CU-05-08.
