Pull #53

The golden failure came from holdings cost formatting: the native engine rounded all cost values to 2 decimal places, but bean-query only does that for cross-currency cost basis.

For Assets:Stocks with 1.156 AAPL @ 10.45 EUR (price, no cost lot), cost falls back to unit currency (1.156 AAPL). Rounding that to 1.16 AAPL broke parity with the CLI.

Fix in query_engine.ex: use full format_decimal/1 when cost_currency == unit_currency, and keep format_cost_decimal/1 (2dp) when they differ (e.g. 3 AAPL → 100 USD from 99.999).

Added a regression test mirroring the tolerance golden fixture. 557 tests pass (golden tolerance compare included when run with --include beancount).
