📄 Description

This adds a language change that requires references from typealiases to the enclosing module to be const.

This is required because typealiases are not late-bound.

Rationale is laid out in SPICE-0007.

Also:

Update documentation to reflect new rules.
Fix Project.pkl; mark method const to not break said rule.
