Overview

This PR adds a per-key price floor to the bonding curve so that sell swaps are rejected when the current price is at or below a configured minimum. Buys are unaffected. Admins can set and read the floor per key, and blocked sells surface a dedicated error and event.

Changes

🛡️ Price Floor Enforcement

• [MODIFY] creator-keys/src/curve_subscriptions_swaps.rs

  • set_price_floor(key_id, floor_price) — admin-only; stores the floor for a single key.
  • get_price_floor(key_id) — returns the configured floor, or zero if none is set.
  • swap() with direction=sell now compares the current curve price against the key's floor before executing; if price ≤ floor, the swap is rejected with PriceFloorBreached carrying the current price and floor.
  • Buy path is untouched.

• [MODIFY] creator-keys/src/events.rs

  • PriceFloorTriggered event emitted on every blocked sell, containing the key, attempted price, and floor.
