[qoryhanisagal]

This pull request implements the features required for Iteration 3 of the project. It introduces methods to enhance the bidding functionality in the Auction and Item classes. The updates include the following:

Key Features

1.	Auction#bidders:
•	Returns an array of unique bidder names (as strings) who have placed bids on any item in the auction.
•	Example output: ["Megan", "Bob", "Mike"].
2.	Auction#bidder_info:
•	Returns a detailed hash with the following structure:
•	Keys: Attendee objects who placed bids.
•	Values: Subhash containing:
•	:budget: The attendee’s budget as an integer.
•	:items: An array of items the attendee has bid on.


Tests

•	Comprehensive unit tests were added for all new methods in the following files:
•	auction_spec.rb:
•	Tests for bidders and bidder_info.
•	item_spec.rb:
•	Test for close_bidding.
•	All tests pass successfully, ensuring correctness of the new functionality.

Implementation Notes

•	The Auction#bidder_info method uses nested loops to iterate over items and attendees’ bids to construct the required hash structure.
•	The Item#close_bidding method utilizes a flag (@bidding_closed) to determine if new bids should be accepted.
