feat: shopper/admin attributes, bundle min/max, catalog rule validation, pricebook segmentation

[field123]

Closes #90

Summary

Brings the legacy SDK in line with recent additions to the upstream PIM (pim.yaml) and shopper Catalog View (catalog_view.yaml) OpenAPI specs. All changes are additive — no breaking changes.

From pim.yaml (admin / PXM)

• shopper_attributes / admin_attributes on products — adds the two { [key: string]: string } maps to PcmProductBase.attributes (the equivalent fields are already on HierarchyBase and NodeBase, so this rounds out the trio).
• Per-option min / max on bundle component options — adds min and max to ProductComponentOption (component-level min/max already exists on ProductComponents).
• Product export columns.include — adds an optional third argument to ExportProducts(filter, useTemplateSlugs, columns) and threads { data: { type: 'product', attributes: { columns } } } through as the request body. Supports individual keys (admin_attributes.cost_of_goods) and wildcards (admin_attributes.*).

From catalog_view.yaml (shopper / catalog)

• Validate on Rules — new POST /catalogs/rules/validate method on the CatalogsRulesEndpoint. Adds CatalogRuleValidatorRequest (with match_type of filter | similarity | conflict | resolve_for_shopper), RuleMeta (similarity_score, active, resolved_for_shopper, release_id), ValidatedRule, and ValidateRulesResponse.
• pricebook_ids on RuleFilter — populates the previously-stub RuleFilter interface with eq and in operators against id, catalog_id, account_ids, customer_ids, channels, tags and the new pricebook_ids. Also adds pricebook_ids?: string[] on RuleBase.attributes.
• Pricebook segmentation product fields — adds available_prices, alternative_prices and available_pricebook_ids on ProductResponse.attributes. Component product metadata also gains alternative_prices. New AvailablePrice, AlternativePrice and PriceTier types.
• ReleaseIndexingCompleteData — new type for the indexing-complete payload ({ data: { status: 'succeeded' | 'failed' } }).

Out of scope

• The EP-Pricebook-IDs-Of-Available-Prices-To-Show request header isn't threaded through the relevant Catalog/Catalogs.Products methods. The request factory already supports additionalHeaders so this could be done as a follow-up; threading it through every method is a larger API surface change worth its own PR.

Test plan

• yarn lint clean
• yarn rollup builds clean (existing CodeFileHref re-export warning is pre-existing on main)
• yarn test — pre-existing environment issue on main (chai module not linked under current Node version) blocks the suite; not introduced here
• Reviewer: spot-check the new types compile against a downstream consumer
