feat: native installer + Docker Hub publish

- install.sh: handles Node.js 18+, ffmpeg, HandBrake CLI, libdvd* on
  apt/dnf/pacman/brew; optional systemd service registration
- README: document installer, accurate system dep table (ffmpeg/ffprobe
  required, HandBrake + libdvd* recommended), libdvdcss legal note
- README: add Docker Hub pull reference (pyr0ball/discarr:latest)
- README: fix misleading 'zero-dependency' framing (no npm deps, but
  system deps like ffmpeg and libdvd* are required)

 ## Install
 
-### From source
+### Native installer (recommended)
+
+Handles Node.js, ffmpeg, HandBrake CLI, and DVD libraries automatically. Supports Ubuntu/Debian, Fedora/RHEL, Arch, and macOS.
 
 ```bash
 git clone https://git.opensourcesolarpunk.com/Circuit-Forge/discarr
 cd discarr
+sudo bash install.sh
 ```
 
-Requirements: Node.js 18+, ffmpeg, ffprobe (for metadata scanning).
+The installer will ask if you want to register a systemd service. Override defaults with env vars:
+
+```bash
+sudo DISCARR_INSTALL_DIR=/opt/discarr DISCARR_PORT=8603 REGISTER_SERVICE=yes bash install.sh
+```
+
+#### System dependencies installed
+
+| Dependency | Required | Purpose |
+|---|---|---|
+| Node.js 18+ | Yes | Runtime |
+| ffmpeg + ffprobe | Yes | Disc metadata scanning, encode dispatch |
+| HandBrake CLI | Recommended | HEVC encoding (falls back to ffmpeg if absent) |
+| libdvdcss | Recommended | CSS-encrypted DVD decryption |
+| libdvdread + libdvdnav | Yes (DVD) | DVD structure and navigation reading |
+
+> **Note on libdvdcss:** Legal in most jurisdictions for personal use. Ubuntu users: `libdvd-pkg` builds it from source. Fedora users: requires RPM Fusion. The installer handles both.
