refactor: add Packet::hasData(), replace 52 position checks and 14 more Lua guards

Browse source 
Add Packet::hasData() for 'has remaining data' checks, replacing 52
verbose getReadPos()<getSize() comparisons across 3 files. Also replace
14 more standalone Lua return patterns with luaReturnNil/Zero helpers.
