Replace hardcoded WotLK protocol constants with a data-driven architecture supporting Classic 1.12.1, TBC 2.4.3, and WotLK 3.3.5a. Each expansion has JSON profiles for opcodes, update fields, and DBC layouts, plus C++ polymorphic packet parsers for binary format differences (movement flags, speed fields, transport data, spline format, char enum layout). Key components: - ExpansionRegistry: scans Data/expansions/*/expansion.json at startup - OpcodeTable: logical enum <-> wire values loaded from JSON - UpdateFieldTable: field indices loaded from JSON per expansion - DBCLayout: schema-driven DBC field lookups replacing magic numbers - PacketParsers: WotLK/TBC/Classic parsers with correct flag positions - Multi-manifest AssetManager: layered manifests with priority ordering - HDPackManager: overlay texture packs with expansion compatibility - Auth screen expansion picker replacing hardcoded version dropdown
