Tracks FactoryBot factory definition files when factories are used.

Factory files are typically loaded at boot time, before coverage starts. This tracker intercepts FactoryBot.factories.find (called by create/build) to record the source file where each factory was defined.

Register via: coverage_map.use(FastCov::FactoryBotTracker)

Defined Under Namespace
