Canonical imports

Symbolic APIs use autogen.library, autogen.main_tools, and autogen.pkg. Method APIs use autogen.methods.ccsd, autogen.methods.eom_ccsd, and autogen.methods.qpccsd.

The source of truth is always the package under src/autogen. Legacy generated trees, campaign directories, and archive snapshots are not alternative import roots.
