Register LLVM source used by LLDB-MI

[Sean McManus (sean-mcmanus)]

Summary

Register the exact llvm-project revision cloned by the LLDB-MI build, normalize the Component Governance manifest to its current schema, and add a focused check that keeps both LLDB-MI build inputs synchronized with the manifest.

This PR was investigated and created by GitHub Copilot in VS Code. Any message starting with ✨Copilot: was sent by Copilot.

Why this matters

The LLDB-MI build consumes two independently pinned Git repositories: llvm-project supplies the LLVM and LLDB source used to create the build environment, while lldb-mi supplies the executable source. The manifest currently registers only lldb-mi, so the component inventory describes only one of the two source inputs used to produce the artifact.

Component inventory is not limited to files copied verbatim into the VSIX. Source fetched and compiled during an artifact build must be associated with the exact revision that was consumed. Registering llvm-project at 0d44201451f03ba907cdb268ddddfc3fa38a0ebd closes that gap without changing the build or the existing lldb-mi registration.

The build template already says its two repository/hash pairs must match the manifest, but comments cannot prevent drift. The new dependency-free validator compares both pairs, accepts the manifest's canonical URL spelling without the optional .git suffix, and fails CI when a registration is missing or stale. It runs before dependency installation in the existing compile-and-test workflow.

Open PR #11566 changes only the existing lldb-mi pin. It remains independent; if it lands, the validator will require its build and manifest hashes to be updated together.

Validation

• npm run test-lldb-mi-component-manifest
• npm run verify-lldb-mi-component-manifest
• npm run test-yarn-lock
• npm run verify-yarn-lock
• Component manifest SchemaStore validation
• Workflow and LLDB-MI template YAML parsing
• git diff --check
