dotnet-inspect: SourceLink and PDB source

Use this skill to get source mapped by the Portable PDB. dotnet-inspect verifies local files and GitHub committed blobs read through --repo against the PDB checksum. A network PDB Source fetch follows redirects permitted by the host transport and returns the body only when it matches that checksum; it does not treat the final destination as source provenance. Use library -S "SourceLink: Integrity" for opt-in verification that every fetchable, non-embedded compiler-source document preserves its attributed repository and revision through redirects. If no usable PDB or checksum-matching source is available locally or through SourceLink, use the always-local decompiler skill.

The checksum proves that returned bytes match the PDB's declaration. It does not independently prove that those bytes are the physical syntax tree that produced a MethodDef; PDB Source names that evidence boundary explicitly.
