Remove NonceCache singleton pattern and replace with fetch_nonce_info function
that directly fetches nonce information from RPC. This simplifies the API by
eliminating cache initialization and state management, making it easier for
users to manage durable nonces.
Replace the global AddressLookupTableCache with a direct fetch function to simplify address lookup table management. This change improves code maintainability by removing global state and makes the API more explicit.
Key changes:
- Remove AddressLookupTableCache and AddressLookupManager
- Add new fetch_address_lookup_table_account function
- Update TradeBuyParams and TradeSellParams to use AddressLookupTableAccount instead of Pubkey
- Update all examples to use the new direct fetch approach
- Update documentation to reflect the simplified workflow
