Add Offer Management to Market Component

[codebestia]

Summary

Introduce offer management to the market module by defining offer data structures, extending the market interface with offer-related APIs, and adding template implementations in the market component. Also includes minor formatting cleanups.

Key Changes

• Data types:
  • Added Offer and OfferStatus in src/types.cairo.
• Interface:
  • Extended IMarket in src/interfaces/imarket.cairo with offer APIs:
    • make_offer, accept_offer, close_offer, get_offer, get_offers, get_open_offers.
• Component:
  • Implemented template/stub functions for offer management in src/components/market.cairo:
    • Added the above offer methods with placeholder logic and default return values.
  • Updated imports to include Offer and OfferStatus.
• Chore:
  • Formatting updates to market.cairo and imarket.cairo.

Files Changed

• Modified: src/components/market.cairo
• Modified: src/interfaces/imarket.cairo
• Modified: src/types.cairo

Notes

• Current implementations are templates/stubs to scaffold the offer flow; storage and state transitions for offers are not yet wired.
• No breaking changes; all changes are additive.

Testing

• No functional logic added yet; follow-up PR will add storage, state transitions, and tests for offer lifecycle.
