Replace the single 3300-line generate-models.ts with declarative provider definitions and ordered rule packs under scripts/model-generation/. Each provider is a defineProvider() call: an upstream source (usually the generic modelsDev() mapper), static models upstream lacks, and rules scoped to that provider. Cross-provider facts live in rule packs applied in a fixed order. Every rule() carries a why, matches models with plain data, and patches them with typed set/replace/apply semantics. Generated model data is unchanged: 1443 models across 41 providers compare equal against a snapshot of the same upstream responses, apart from a now stable key order. Committed models.generated.ts and provider shards are byte-identical. Also: - Bring packages/ai/scripts under tsgo and biome; the old generator had 20+ type errors that nothing checked. - Add --upstream-snapshot <dir> to record and replay upstream catalogs and --explain <provider>:<model> to list the rules applied to a model. - Report rules that matched no model so stale corrections get removed. - Export parseRadiusGatewayConfig so the generator can replay Radius too.
