Move ELF, PE and Mach-O container parsing into a shared native owner. Go alone selects and validates Go build-info sections, so unrelated malformed Go metadata no longer blocks Rust dependency or IL2CPP inspection. Remove the superseded Go-specific container representation and migrate all consumers. Adapted from draft PR #5510 without asserting human PR readiness. Validation: 51 compiled CLI/MCP acceptance tests across Rust, Go and IL2CPP; 186 shared-reader tests; full check:ci passed. Three public synthetic-file probes reproduce the baseline Rust refusal and validate the fixed SDK-advertised MCP output, artifact digests and unchanged bytes. The exact zero-address nonallocated ELF case now succeeds for Rust while Go still reports invalid_format. No target execution or real compiler-artifact qualification was performed; no performance improvement is claimed. Closes #3398
