fix: IntraIOManager batch thread + AutoCompiler Windows support

- Re-enable batch flush thread for low-frequency message batching
- Fix JSON type error in routing stats logging (.get<size_t>())
- Add Windows/MinGW support to AutoCompiler (mingw32-make, NUL)
- Fix TankModule.h linter merge bug (add comment between lines)
- Add Windows platform check for make command in test_01
