feat: export PromotedOfferingsRequirement and PromotedOfferingsAssetRequirements, sync latest schemas (#133)

- Export PromotedOfferingsRequirement enum (7 values: si_agent_url, offerings,
  brand.logos, brand.colors, brand.tone, brand.assets, brand.product_catalog)
  from adcp and adcp.types public APIs
- Export PromotedOfferingsAssetRequirements model (requires: list[...]) from
  adcp and adcp.types public APIs
- Sync 29 upstream schema updates and regenerate types (new: audience-member,
  sync-audiences request/response; updated: format, targeting, capabilities,
  task-type, and various response schemas)
- Add 14 tests covering enum values, string coercion, JSON round-trip,
  minItems constraint, SI agent use cases, and extra fields preservation
