macp package.json had a pre-existing exports map with default: './src/index.ts'
which broke any consumer that loaded the compiled mosaic CLI via node (mosaic
--help, mosaic <cmd> --help). Every other workspace package points at
./dist/index.js — align macp with the rest.
Adds packages/mosaic/src/cli-smoke.spec.ts — the CU-05-10 integration smoke
test that asserts every register<Name>Command from the eight sub-packages
(auth, brain, forge, log, macp, memory, queue, storage) plus config attaches a
top-level command and that its help output renders without throwing. Running
this locally after the macp fix confirms mosaic --help and mosaic <cmd> --help
exit 0 for all nine commands.
