Description

按照 https://deb-sig.github.io/double-entry-generator/examples/advanced-rules/ 的示范写了一条含有 conditions 键的高级规则，结果生成账单中的所有条目都变成了该条规则指定的同样的 targetAccount. 就好像 conditions 这个条件没有起作用一样，让所有的条目 pass 了。试了几种写法都不行。请教 conditions 怎么用？

Research direction
The user reports that the `conditions` key in advanced rules does not filter transactions as expected, causing all entries to match. The issue likely lies in the rule evaluation logic. Start by examining the rule engine code in the repository, particularly the parsing and application of conditions. Look for where conditions are checked against transaction data. Compare the implementation with the documented behavior in the advanced rules example. Check if the condition expression is correctly evaluated or if there is a default fallback that always passes. Review the comments in the issue for any additional clues, and consider writing a simple test case to reproduce the bug.
