Add explicit gfx1200/gfx1201 builds, runtime selection and per-target code objects. Guard staging, packaging and installation against mixed architectures; retain gfx1201 compatibility and strict K/M arithmetic. Adapt realdody's target configuration and MSVC binary16/BOOL portability fixes from ae530b0. Do not import its forced gfx12 layout on RDNA3. Add exhaustive binary16 and C++/PowerShell target contract regressions. Validation: 20 CTest gates on RX 9070 XT; four software-only gfx1200 gates; MSVC portability compile checks; exact 4K K async and M control outputs; isolated package install/restore and mixed-target rejection tests. No physical gfx1200 validation is claimed. Co-authored-by: realdody <[email protected]>
