[Feature] Make the validation process more robust

[lty12b9b0a1]

The current validation procedure in the default translator and discriminator is both fragile and strict; a slight change to the project name, file names, or project structure may cause validation to fail.

Consider making the procedure more robust, like adding an additional simple helper agent to handle this kind of “last-mile” smoothing, resolving non-technical issues such as file-name mismatches and similar inconsistencies.
