MetalNX v2.0.6: Autonomous Engine Root Discovery & Self-Healing Pipeline

What's Changed in v2.0.6

• Fixed Repository Root Discovery: Resolved the error cannot find the repository root above /Applications/MetalNX.app/Contents/Resources/scripts/build_ipa_from_nsp.py. The launcher now verifies that an engine root must contain the full engine tree (dm/tools/nx_extract/Program.cs), explicitly preventing the app's internal Contents/Resources directory from falsely masquerading as a repository root.
• Dynamic Multi-Location Fallback: Added robust multi-tier fallback lookup in build_ipa_from_nsp.py checking NXNATIVE_ROOT, DM_ROOT, saved preferences, ~/Library/Application Support/nxnative/engine, and standard developer roots.
• Standalone spirv-cross & nx_extract Bundling: Fully bundled standalone binaries for zero-.NET and zero-Homebrew dependency requirements.
• Self-Healing Build Directory Cleanup: Automatically deletes stale and incomplete intermediate files from failed previous runs.
• Automated Test Suite Expansion: Added Unit Test 10 verifying app bundle protection and dynamic repository discovery (47/47 tests passing).

Requirements

• macOS 13.0+ (Ventura, Sonoma, Sequoia)
• Apple Silicon Mac (M1 / M2 / M3 / M4)
