fix(native): return true for collectgarbage('isrunning') and use dynamic vector for pcall/xpcall arguments

[esrrhs]

Round 21 Deep Audit Fixes

1. collectgarbage('isrunning') Return Type Bug:

   • Bug: In src/native/native_basic.cpp, collectgarbage('isrunning') returned integer 0 instead of boolean true.
   • Fix: Returns inter::NativeToFakeluaBool(state, true) for 'isrunning' option per Lua 5.3+ standard specification.
   • Added unit test in test_basic_collectgarbage.lua.

2. pcall/xpcall Dynamic Vector Argument Allocation:

   • Fix: Replaced hardcoded 16-element stack array with std::vector to allow unconstrained variadic parameter passing to protected call closures.
