fix: remove Node.js from actual path location on Act runner

The Act runner has Node 18 at /opt/acttoolcache/node/18.20.3/x64/bin/,
not at /usr/local/bin/. Use $(dirname "$(which node)") to find and
remove the actual binary location before installing Node 22.

+- **Xcode Command Line Tools** — required for the C/C++ toolchain and system headers:

+No additional system libraries are needed — macOS includes WebKit natively.

+### 2. Install Rust targets (universal binary)

+To build a universal binary that runs on both Apple Silicon and Intel Macs:
+
+```bash
+rustup target add aarch64-apple-darwin x86_64-apple-darwin
+```
+
+### 3. Install frontend dependencies
+
+```bash
+cd app

+
+### 4. Build
+
+For a universal binary (recommended for distribution):
+
+```bash
+npx tauri build --target universal-apple-darwin
+```
+
+For the current architecture only (faster, for local development):
+
+```bash
