#10 — Add cross-platform VS Code editor adapter for MrBuild LSP proof

What to build

Create the buildable VS Code Editor Adapter foundation in F# and Fable. Pin and consume the Ionide VS Code helper source, preserve its isolated Paket/Fable/Yarn/Webpack toolchain, define the extension metadata, and add CI-safe VS Code-specific build targets to the existing FAKE pipeline.

Acceptance criteria

• The adapter compiles from F# to the JavaScript extension bundle.
• The pinned Ionide helper source and its binding project are consumed reproducibly.
• The isolated helper toolchain does not alter MrBuild’s existing .NET package graph.
• VsCodeRestore, VsCodeBuild, and VsCodePackage are available through the existing cross-platform build wrappers.
• The generated bundle has the VS Code activation metadata required for Extension Development Host launch.
• The CI-safe targets do not launch a GUI editor.

Blocked by

None — can start immediately.

Start with the existing FAKE pipeline and its cross-platform build wrappers, then inspect the pinned Ionide helper source, binding project, and isolated Paket/Fable/Yarn/Webpack toolchain described here. Done means the F# adapter produces a JavaScript extension bundle, exposes VsCodeRestore, VsCodeBuild, and VsCodePackage, includes activation metadata, preserves the existing .NET package graph, and remains CI-safe without launching a GUI editor.
