The Pi monorepo

• §2.1: corrected the shared package version to 1.3.0.
• §2.8: added a paragraph on model-catalog compatibility. Before publishing, scripts/check-model-catalog-compat.mjs type-checks the latest release's pi-ai against its built-in models with the new catalog laid over them. The cutoff MINIMUM_PI_VERSION now lives in scripts/model-catalog-minimum-version.mjs.
