Improves :errors of invalid errors to be more user friendly.
Also enable closed-value validation optionally as it is useful
to have higher data quality for non RTC graphs
by introducing logseq.cli.* for internal API usage.
Also refactor existing api tools to share same implementation as
local tools. This fixes a couple bugs w/ the api tools as get-page
was returning :block.temp/* keys and list-pages were returning uuids under
the id key unlike all other responses
Lazy load namespaces as start time goes up with more required namespaces
external to nbb-logseq or node. CLI now only loads ~6 namespaces instead
of 55 namespaces at start and then lazy loads a command ns as needed
