v0.2.0 - Weekly Deals

Delivery time-slots now work for accounts whose login doesn't return an
address, plus new bulk product lookups and a weekly-deals helper.

Fixed

• Delivery slots when login omits an address. The Rohlik login response
  doesn't always include a delivery address (data.address can be null),
  which left address_id unset and made delivery.get_next_slots() return
  None. It now falls back to the saved delivery-address list, prefers the
  address you're currently delivered to (isDeliveredTo), and caches the
  resolved id so later calls stay a single request.

Added

• delivery.get_addresses() — list the account's saved delivery
  addresses.
• delivery.get_active_address_id() — resolve the delivery address id
  used for time-slot lookups.
• products.get_cards(product_ids) — fetch basic data for many products
  in a single request (bulk /products/card endpoint).
• products.get_week_sales() — this week's deals ("Akce týdne"),
  enriched with product data in one follow-up request.
• ProductCard model — a trimmed, meaningful product shape: id,
  name, brand, amount, unit, price (sale price when on sale, else
  regular), original_price, unit_price, currency, on_sale,
  sale_valid_till, in_stock. Website display-only fields are omitted.
• AuthManager.address_id setter — to cache a resolved address.

Compatibility

• No breaking changes. Public API and existing return types are unchanged;
  all additions are new methods/model.
• Requires Python 3.13+.
