feat: add cross-platform release pipeline and app icons

- Update tauri.conf.json with multi-platform bundle config (macOS unsigned, Windows unsigned)
- Add app icon (1024x1024 source) and generate all required sizes (png, icns, ico)
- Add generate-icons.sh script for regenerating icons from source PNG
- Add GitHub Actions release workflow for 4-target parallel builds (macOS ARM/x64, Linux, Windows)
- Simplify release.sh with tag-based publish instructions

+
+            **macOS** (unsigned — requires manual approval):
+            - Download the `.dmg` for your architecture (ARM for Apple Silicon, x64 for Intel)
+            - Open the DMG and drag ClawPal to Applications
+            - First launch: right-click the app → Open, or run `xattr -cr /Applications/ClawPal.app`
+
+            **Windows** (unsigned — SmartScreen will warn):
+            - Download the `.exe` (NSIS installer) or `.msi`
+            - If SmartScreen blocks: click "More info" → "Run anyway"
+
+            **Linux**:
+            - `.deb`: `sudo dpkg -i clawpal_*.deb`
+            - `.AppImage`: `chmod +x ClawPal_*.AppImage && ./ClawPal_*.AppImage`
+          releaseDraft: true
