Scaffolds the #2 POC: a runnable, non-shippable standalone VS Code extension on @cline/sdk — validating Approach A (own coauthoring UI on the Cline SDK, no fork). Per issue #2 (epic #1) and ben.stull/rfc-app#48.

What's here

Extension entry (src/extension.ts) registering Cowriting: Show Cline SDK Info.
vscode-free SDK driver (src/cline.ts) — fetchSdkSummary() drives @cline/sdk (pure, key-free getCoreBuiltinToolCatalog() + CORE_BUILD_VERSION).
esbuild CJS bundle (3.3kb) keeping vscode + @cline/sdk external.
F5 launch config, unit test, README, and the implementation plan.

Key design call

@cline/sdk is ESM-only (Node ≥22) and uses createRequire(import.meta.url), so it cannot be bundled into a CJS extension (verified: import.meta.url → undefined → throw). It is kept external and loaded at runtime via dynamic import(). Empirically de-risked before coding.

Verification (green)

npm run typecheck clean · npm test passes (fetchSdkSummary() returns 0.0.46 + the 9 builtin tools incl. read_files) · npm run build → out/extension.cjs.
Bundle loaded with a stubbed vscode; activate() runs and registers its disposables.
Operator step (GUI): press F5, run the command — notification shows Cline SDK 0.0.46 loaded — 9 builtin tools.

POC scaffold: extension manifest + tooling config (Feature #2 ) b343f0754a

Manifest declares the cowriting.showClineSdkInfo command; esbuild + vitest +
tsc tooling. @cline/sdk@0.0.46 as a runtime dependency. Per issue #2 (epic #1).

POC: vscode-free @cline/sdk driver with unit test (Feature #2 ) 33bff2b130

fetchSdkSummary() dynamic-imports the ESM-only SDK and returns its build
version + builtin tool catalog (pure, key-free). Kept vscode-free so it is
unit-testable in Node; test asserts a semver version and the read_files tool.

POC: extension entry + esbuild bundle (Feature #2 ) 80083c1230

activate() registers showClineSdkInfo, which renders the SDK summary to a
notification and output channel. esbuild bundles to CJS, keeping vscode and
@cline/sdk external (the ESM SDK loads via runtime dynamic import).
