chore: bump version to 0.4.0

This also fixes some bugs with referencing figures in elements such as align,
this also generalizes the logic to handle nesting.

#__format-ref show rule now goes through #custom-ref most of the time,
so builtin #ref can be used instead.

Equations are now referenceable and respect numbering per sections.
