Function scorePath

agent/filefinder/text.go:252–288

scorePath computes a relevance score for a candidate path against a query. The score combines several signals: basename match, basename prefix, exact segment match, word-boundary hits, longest contiguous run, and penalties for depth and length. A return value of 0 means no match (the query is not a
