Foundation for WoW-compatible addon support: - Vendor Lua 5.1.5 source as a static library (extern/lua-5.1.5) - TocParser: parses .toc files (## directives + file lists) - LuaEngine: Lua 5.1 VM with sandboxed stdlib (no io/os/debug), WoW-compatible print() that outputs to chat, GetTime() stub - AddonManager: scans Data/interface/AddOns/ for .toc files, loads .lua files on world entry, skips LoadOnDemand addons - /run <code> slash command for inline Lua execution - HelloWorld test addon that prints to chat on load Integration: AddonManager initialized after asset manager, addons loaded once on first world entry, reset on logout. XML frame parsing is deferred to a future step.
