Pull request overview
Updates the security guidance doc to clarify how to classify security issues vs bugs when dealing with untrusted Wasm inputs versus trusted AoT outputs, and to refine the reporting checklist language.
Changes:
- Adds explicit guidance distinguishing untrusted WebAssembly binaries from trusted, toolchain-produced AoT binaries.
- Clarifies when AoT-related crashes/sandbox breaches should be treated as security issues (toolchain emission) vs non-security bugs (malformed/manipulated AoT artifacts).
- Edits the “crash or hang” checklist section and removes a formatting artifact.
