* fix(domain): admit Qualcomm Hexagon (EM_HEXAGON, 164) ELF binaries Resolve missing ELF admission case for Qualcomm Hexagon DSP targets (e_machine = 164, EM_HEXAGON). - Add 'hexagon' to BINARY_ARCHITECTURES and HeaderArchitecture - Map EM_HEXAGON (164) in elfArchitecture() to 'hexagon' - Include 'hexagon' in GhidraProvider's SUPPORTED_ARCHITECTURES - Gracefully decline 'hexagon' with Ghidra-directed diagnostic in Hopper and IDA - Add unit tests for Hexagon ELF parsing and adapter admission checks Fixes #4781 * fix(hopper,ghidra): add Ghidra guidance to Hopper Hexagon refusal and add Ghidra admission regression test
