Break down purchase receipts by cost/commission, harden XML validation and state I/O

2026-08-18T15:19:50Z

Adds a full pre-load validation pass for GM XML seeds (ids, names, options, commission, LMSR liquidity), replaces IO.print with System.out, and surfaces detailed error messages across load/save commands instead of generic failures.

Add XML schema validation, split build scripts by module, rename BuyMenuCommand to PlaceOrderMenuCommand

2026-08-18T06:52:47Z

Introduces XMLValidatorV1 and deserializer/adapter classes for events, ledgers, markets, users, and trading mechanisms. Replaces the monolithic build.bat/run.sh scripts with per-module tools (_util.sh, build.sh, package.sh, test.sh) that compile in dependency order.
