name: VS Code extension package

# Gates the op-vscode extension (typecheck + unit tests + esbuild bundle) and
# packages a platform-neutral .vsix artifact on every change. The daemon
# binary + wasm bundle are NOT embedded yet (the extension probes
# <workspace>/target/debug/op-host-web-server or `openpencil.dev.daemonPath`);
# per-platform vsix bundling lands with the packaging plan (Plan 3).
