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
Add Meteora DAMM V2 trading protocol with instruction builder, type definitions, and fixed_output_token_amount parameter for precise output control. Update all examples and documentation.
This refactoring migrates protocol-related type definitions from solana-streamer-sdk to local modules:
- Add local type files: bonk_types.rs, pumpswap_types.rs, raydium_amm_v4_types.rs, raydium_cpmm_types.rs
- Add BorshDeserialize support for all types
- Refactor BondingCurveAccount to support Borsh deserialization
- Update import paths across all protocol utility modules (bonk, pumpfun, pumpswap, raydium)

- Synchronize English and Chinese documentation
BREAKING CHANGE:
- Removed TradeSwapParams struct
- Modified field names in TradeBuyParams and TradeSellParams
- Existing code needs migration to use new parameter structure

- Update bonk_copy_trading example to use new swap method instead of buy/sell
- Expand trading parameters documentation with TradeSwapParams details
- Fix SOL_TOKEN_ACCOUNT constant definition
- Add USD1 token support (Bonk protocol only)
- Enhance account management and optimization options for token swaps
- Change recent_blockhash from required to optional parameter
- Replace separate nonce_account and current_nonce with unified durable_nonce
- Update all examples and documentation to reflect API changes
- Improve nonce cache usage pattern for better developer experience
BREAKING CHANGE: TradeBuyParams and TradeSellParams API has changed
- recent_blockhash is now Option<Hash> instead of Hash
- nonce_account and current_nonce fields replaced with durable_nonce: Option<DurableNonceInfo>
- Add nonce_account and current_nonce to trade parameters
- Remove hardcoded NonceCache dependency from nonce_manager
- Update examples and documentation for new nonce usage
- Fix nonce documentation errors and improve clarity
