feat(parser): add dot notation for sub_concept declarations

Browse Source 
Changed sub_concept syntax from heuristic parent extraction to
explicit dot notation: `sub_concept Parent.Name { ... }`

The old syntax inferred the parent concept from the name using
uppercase letter heuristics. The new syntax makes the parent
concept explicit and unambiguous.

Added type_system_tests module with comprehensive tests.
