Andreas Lierschaft 08481e3906 Add standalone pack tooling (PackList/PackMake/PackVerify)
Automates the .eix/.epk repacking step that was previously done via the
EterNexus.exe GUI, using the real CEterPack class so output is guaranteed
read-compatible with the game client. PackList inspects an existing pack's
entries, PackMake rebuilds a pack from a source folder, PackVerify
byte-compares a pack's contents against source to confirm round-trip
correctness.

// Round-trip verification tool: opens a pack read-only, reads every entry via
// the same CEterPack::Get() path the game engine uses, and byte-compares it
// against the corresponding file under a source folder.
//
// Usage: PackVerify.exe <packFolder> <dbname> <sourceFolder>
// e.g. PackVerify.exe "Y:\scratch\pack" root "Y:\Metin2Dev\Exec_Client\Eternexus\root"
