- Rename dbt project from toronto_housing to portfolio
- Restructure dbt models into domain subdirectories:
- shared/ for cross-domain dimensions (dim_time)
- staging/toronto/, intermediate/toronto/, marts/toronto/
- Update SQLAlchemy models for raw_toronto schema
- Add explicit cross-schema FK relationships for FactRentals
- Namespace figure factories under figures/toronto/
- Namespace notebooks under notebooks/toronto/
- Update Makefile with domain-specific targets and env loading
- Update all documentation for multi-dashboard structure
This enables adding new dashboard projects (e.g., /football, /energy)
without structural conflicts or naming collisions.
