feat: enhance native binary resolution and add bundled Node.js runtime

- Refactored gelectron.js to improve native binary discovery with additional paths and environment variable support.
- Implemented a function to find the Node.js runtime, allowing bundled Node.js to be used when available.
- Updated package.json to include gelectron-packager as a CLI command.
- Enhanced gelectron-packager.js to locate installed gelectron runtime and added compatibility for bundled Node.js.
- Modified install-release.sh to download and install a private Node.js runtime alongside the gelectron binary.
- Updated NSIS installer script to include bundled Node.js runtime.
- Enhanced AppImage and DMG packaging scripts to include Node.js runtime.
- Added clipboard, nativeTheme, and screen modules for Electron compatibility.
- Implemented native bridge request handling for clipboard operations.

 ```
 
+### Download a native installer (double-click, no tools needed)
+
+Every new release tag (pushed as `v*`) is pre-compiled in CI and published as
+platform-native, double-clickable installers on the [Releases page]:
+
+| Platform | Installer | What it does |
+|---|---|---|
+| macOS | `Gelectron-<version>-arm64.dmg` / `-x64.dmg` | Contains `Install gelectron.pkg`, which installs the runtime + compat layer **plus a private Node.js** to `/usr/local/lib/gelectron` and symlinks `gelectron` into `/usr/local/bin` |
+| Windows | `Gelectron-<version>-x64.exe` / `-arm64.exe` | NSIS installer → `C:\Program Files\Gelectron` (runtime + compat + private Node.js), adds it to the system PATH, Start Menu + uninstaller |
+| Linux | `Gelectron-<version>-x86_64.AppImage` / `-aarch64.AppImage` | Fully self-contained (runtime + compat + private Node.js), just run it |
+
+After installing, `gelectron /path/to/electron-app` works from anywhere, and no
+system Node.js install is required — every installer bundles its own runtime.
+
+Apps packaged with `gelectron-packager` are equally self-contained: double-click
+a packaged app and it runs with no gelectron and no Node.js installed.
+
+> macOS installers are ad-hoc signed (no Developer ID), so on another Mac the
+> first launch shows a Gatekeeper "unidentified developer" warning — right-click
+> → Open to run it.
+
+### Install from GitHub Releases (no npm)
+
+Every new release tag (pushed as `v*`) is pre-compiled in CI and published as
+a self-contained installer archive. Install the latest pre-built runtime with
+a single command — no Rust toolchain, no npm:
+
+```bash
+# macOS / Linux
+curl -fsSL https://raw.githubusercontent.com/mileswolfallen2/gelectron/main/scripts/install-release.sh | bash
+
+# Windows (PowerShell)
+irm https://raw.githubusercontent.com/mileswolfallen2/gelectron/main/scripts/install-release.ps1 | iex
+```
+
+The installer downloads `gelectron-<version>-<platform>-<arch>.tar.gz` (or
+`.zip`) from the latest GitHub Release and puts the `gelectron` binary plus
+the JS compatibility layer into `~/.local/bin` (macOS/Linux) or
+`%LOCALAPPDATA%\gelectron\bin` (Windows). Customize with:
+
+```bash
+bash scripts/install-release.sh --version v0.1.1   # specific tag
+bash scripts/install-release.sh --prefix ~/bin     # custom location
+bash scripts/install-release.sh --uninstall        # remove
+```
+
+Archives can also be downloaded directly from the [Releases page] and
+unpacked manually — the binary just needs the `compat/` folder next to it.
+
 > The `gelectron-core` npm package is the recommended distribution channel. Building from source (below) is only needed if you're developing Gelectron itself or want the bleeding-edge version.
