This PR addresses the build failures in the GitHub Actions workflow by fixing the Luau compatibility issues:

1. Added `luau_fixes.h` to fix problematic Lua declarations:
   - Resolves "Expected parameter declarator" error at line 182 in lua.h
   - Fixes "Unknown type name 'LUALIB_API'" errors in lualib.h
   - Properly defines missing macros and function declarations

2. Added `source/cpp/luau_fixes.cpp` with implementations for required functions:
   - Replaces static function pointers with real implementations
   - Provides proper error reporting functions
   - Fixes linker errors by implementing missing functions

3. Created an improved build workflow in `fixed_build.yml` that:
   - Shows ALL errors that occur during the build process
   - Automatically adds the fixes to source files
   - Performs detailed error analysis and reporting
   - Properly builds Dobby as a required dependency

The build should now succeed with these changes. The workflow has been enhanced to show full error output.

This PR implements a completely reworked approach to fix the Lua compilation issues:

1. **Direct Header Patching:**
   - Created `lua_wrapper.h` and `lua_wrapper.c` that define all needed types before Lua headers
   - Directly patch source files to include our wrapper first
   - Fix lua.h by removing the problematic static function pointer

2. **Real Implementations:**
   - Proper function implementations for lua_pcall and error handling
   - Defined all necessary macros (LUA_API, LUALIB_API, etc.) in one place
   - Fixed forward declarations and function signatures

3. **Improved Build Process:**
   - Enhanced build workflow that directly addresses all compilation errors
   - Better error reporting to identify problems
   - Clear step-by-step patching of problematic files

This approach directly fixes the error "Expected parameter declarator" and "unknown type name 'LUALIB_API'" by properly defining all dependencies before including Lua headers.
