What's Wrong?

VS Code extension fails to activate on Windows. Clicking the Claude Code icon in the editor title bar shows: "command 'claude-vscode.editor.openLast' not found"

Root cause: extension.js contains a hardcoded GitHub Actions runner path passed to module.createRequire(), which fails on Windows:

var eG = require("node:module")
var H1 = eG.createRequire(
"file:///home/runner/work/claude-cli-internal/claude-cli-internal/build-agent-sdk/sdk.mjs"
)

What Should Happen?

Extension activates successfully and Claude Code panel opens.
