Add integration test confirming the bonding curve price increases monotonically with each successive buy

[Chucks1093]

Summary

The bonding curve must guarantee that each successive buy increases the price. An integration test should execute ten sequential single-key buys and assert the price returned by get_price strictly increases after each one.

Scope

• Deploy the contract and record get_price before any buy
• Buy one key, record price; repeat ten times
• Assert each recorded price is strictly greater than the previous
• Assert the price after selling one key is strictly less than the price before the sell
• Assert get_price at supply 0 equals the configured base price

Acceptance Criteria

• Price strictly increases after each sequential buy
• Price strictly decreases after a sell
• Price at supply 0 equals base price
• All ten price snapshots are monotonically increasing

ETA: 12 hours

My approach:
I’ll deploy the bonding curve, capture the initial base price, then perform ten sequential single-key buys while recording the price after each transaction.

I’ll assert that every price strictly increases, then sell one key and verify the price decreases, and finally confirm supply zero returns the configured base price.
