Module order_builder 

Order builder for the Polymarket CLOB exchange.

Centralizes all order construction logic:

• Limit and market order building
• Order validation (side, TIF, quote_quantity)
• EIP-712 signing
• Maker/taker amount computation

Amounts are converted from human-readable decimals to on-chain base units (pUSD 10^6 / CTF shares 10^6) by truncating to USDC_DECIMALS (6) decimal places and extracting the mantissa as an integer.

The builder produces signed PolymarketOrder structs ready for HTTP submission.
