fix(native): preserve parsed section and architecture facts

Browse Source 
Classify lipo parse failures once for native and artifact consumers, retain valid read-only ELF ranges independently of optional section names, and map IL2CPP reader architecture through the existing CPU identity owner before Mach-O parsing.

Regression-first checks reproduced malformed lipo output, lost unnamed-section compiler paths, and the amd64/x86_64 adapter mismatch. Focused parser, artifact, Rust CLI/MCP, Go, and IL2CPP controls passed; authored fixtures do not establish real-provider behavior.

Fixes #5982

Fixes #3397
