dsh-windows-readiness-proof: Verification of Readiness Evidence for Managed Windows Hosts

`dsh-windows-readiness-proof` is an MIT-licensed DSH plugin (requiring Node.js >= 22) used to verify whether sanitized and SHA-256-fixed Windows host observable evidence meets the prerequisites of the DeepSeek Harness. The plugin is positioned as an evidence verifier; it does not collect data nor perform remediation, but instead performs deterministic validation on existing evidence and generates audit artifacts. Its core functionality includes two CLI entry points, `inspect` (to view status) and `verify` (to execute validation and output results), as well as corresponding DSH/MCP tools. The plugin adopts a "Fail closed" strategy, failing for issues such as missing, expired, malformed, suspected sensitive information, or policy mismatches.
