Implement the kernel_file module that collects file metadata,
including license identifier for source files, SHA-256 hash,
Git blob object ID, an estimation of the file type, and
whether files belong to the source, build, or output SBOM.

Add infrastructure to serialize an SPDX graph as a JSON-LD
document. NamespaceMaps in the SPDX document are converted
to custom prefixes in the @context field of the JSON-LD output.
The SBOM tool uses NamespaceMaps solely to shorten SPDX IDs,
avoiding repetition of full namespace URIs by using short prefixes.

Implement command graph generation by parsing .cmd files to build a
dependency graph.
Add CmdGraph, CmdGraphNode, and .cmd file parsing.
Supports generating a flat list of used source files via the
--generate-used-files cli argument.
