Pull request overview

This PR migrates the repository toward a Scientific Python “cookiecutter” style project layout, with updated packaging, docs structure, and CI/CD, while adding/relocating a large set of tests and support modules.

Changes:

• Reworked documentation layout under docs/ (Sphinx config + API reference scaffolding) and adjusted notebook execution + docs workflows accordingly.
• Added multiple new modules and extensive test suite additions/updates, plus new CI/CD workflows and Dependabot config.

In the portfolio_choice block, dynamics: is indented under shocks:, so YAML will treat it as another shock entry rather than a sibling section. Fix the indentation so dynamics is at the same level as shocks and reward.

CD is configured to run on pushes to main, but other workflows still target master. Align the branch filters so releases/builds run from the repo’s default branch consistently.

CI is configured to run on pushes to main, but other workflows in this repo (e.g. .github/workflows/examples.yml) still target master. Align the branch filters so CI/CD reliably run on the default branch.
