d0f32edba7 fix: Repair data pipeline with StatCan CMHC rental data 
- Add StatCan CMHC parser to fetch rental data from Statistics Canada API
- Create year spine (2014-2025) as time dimension driver instead of census
- Add CMA-level rental and income intermediate models
- Update mart_neighbourhood_overview to use rental years as base
- Fix neighbourhood_service queries to match dbt schema
- Add CMHC data loading to pipeline script

Data now flows correctly: 158 neighbourhoods × 12 years = 1,896 records
Rent data available 2019-2025, crime data 2014-2024

053acf6436 feat: Implement Phase 3 neighbourhood data model 
Add schemas, parsers, loaders, and models for Toronto neighbourhood-centric
data including census profiles, crime statistics, and amenities.

Schemas:
- NeighbourhoodRecord, CensusRecord, CrimeRecord, CrimeType
- AmenityType, AmenityRecord, AmenityCount

Models:
- BridgeCMHCNeighbourhood (zone-to-neighbourhood mapping with weights)
- FactCensus, FactCrime, FactAmenities

Parsers:
- TorontoOpenDataParser (CKAN API for neighbourhoods, census, amenities)
- TorontoPoliceParser (crime rates, MCI data)

Loaders:
- load_census_data, load_crime_data, load_amenities
- build_cmhc_neighbourhood_crosswalk (PostGIS area weights)

Also updates CLAUDE.md with projman plugin workflow documentation.
