chore: remove lerna

This was a premature optimization of workspace handling.
Lerna tries to be clever and cache build artefact, etc, but the step
to decide what packages to build takes more than 5s.

For now, using workspaces feature of npm.

Note that npm execute scripts in the order of the `workspaces` field of
`package.json`.
