Replaced fmt, strings, sort, os, io, sync, encoding/json, path/filepath, errors, log, reflect with core.Sprintf, core.E, core.Contains, core.Trim, core.Split, core.Join, core.JoinPath, slices.Sort, c.Fs(), c.Lock(), core.JSONMarshal, core.ReadAll and other CoreGO v0.8.0 primitives. Framework boundary exceptions preserved where stdlib types are required by external interfaces (Gin, net/http, CGo, Wails, bubbletea). Co-Authored-By: Virgil <virgil@lethean.io>
