Model quick cleanups

[dfsnow]

Just to get started:

• Remove individual PIN-level report (superseded by PINVAL)
• Cleanup analysis section resulting from Add descriptive stats for categorical variables #257
• Add README section / docs on reports vs analyses
• Considering moving some sections of the README into docs/
• Remove CI calculations from the evaluate stage
• Bump versions for pre-commit hooks and GitHub Actions

This is such a tiny nitpick, but while we're here, I'd also propose modifying how the model handles char_apts. Specifically, this blob in the ingest handles some recoding that I wonder might be handled more gracefully elsewhere in our architecture.

Notes from pre-2025 meeting:

• terraform fix (fix error thrown from github action run)
• params, multicard_yoy_cap which caps the yoy change for the smaller property: let's check this out, time permitting

Checklist for running 2025:

• update years in params.yaml
• need 2025 land rates (forward-fill land rates from prior tri, or create averages from existing data in ias?)
• could be fun to try make the linear model really good, by testing some polynomials and removing some categorials
