feat(compliance): implement ACT4 strict compliance flow with ELF runner

add functional compliance_runner with ELF loading, memory model, symbol-based signature dump, and tohost handling; wire compliance subdir/target in CMake; upgrade run_compliance.py for ACT4 suite mapping, robust binary/reference discovery, strict signature comparison, and aggregate suites (rv64g/rv64full).
