Function encode_trade_flags 

pub const fn encode_trade_flags(flags: &TradeFlags) -> u8

Encode trade flags (order flags + signing scheme) as a single byte bitfield.

Mirrors encodeTradeFlags from the TypeScript SDK.

Arguments

• flags — the trade flags to encode.

Returns

A u8 bitfield combining order flags (bits 0-4) and signing scheme (bits 5-6).
