feat: refactor trading API and add multi-token type support (v1.2.0)

- Bump version to 1.2.0
- Remove TradeSwapParams to simplify API structure
- Add TradeTokenType enum supporting SOL/WSOL/USD1 tokens
- Standardize parameter naming: sol_amount → input_token_amount, token_amount → input_token_amount
- Refactor account management parameters: create_wsol_ata → create_input_token_ata etc.
- Update all example code to use new API
- 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
