feat: add GOG Bannerlord launch support — alternative to Steam

- Extend BannerlordRuntime to detect GOG executable (Program Files (x86)/GOG Games/...)
- Add launch(source=) method accepting "steam", "gog", or "auto"
- gog_installed flag in RuntimeStatus, ready property accepts Steam OR GOG
- CLI: --source flag selects which version to launch
- Update bannerlord_verify_runtime.sh to detect GOG separately
- Document GOG install, path, and launch in BANNERLORD_RUNTIME.md

Closes #721

+## GOG Version Support
+
+The runtime also supports the GOG version of Bannerlord (no Steam required).
+
+### Installing GOG Version
+
+1. Download the GOG Windows installer from your GOG library (BannerlordSetup.exe)
+2. In Whisky, open the Bannerlord bottle
+3. Run the GOG installer inside the bottle
+4. Install to: `C:\Program Files (x86)\GOG Games\Mount & Blade II Bannerlord\`
+
+The GOG executable will appear at:
+```
+drive_c/Program Files (x86)/GOG Games/Mount & Blade II Bannerlord/bin/Win64_Shipping_Client/Bannerlord.exe
+```
+
+### Launching GOG Version
+
+```python
+from bannerlord_runtime import BannerlordRuntime
+
+rt = BannerlordRuntime()
+# Auto-select: Steam if present, else GOG
+rt.launch(source="auto")
+
+# Force GOG
+rt.launch(source="gog")
+```
+
+Or from the command line:
+```bash
+python -m nexus.bannerlord_runtime --source gog
+```
+
+The verification script (below) detects both Steam and GOG installs.

-2. **Repository Structure:** timmy-home contains core identity files
-3. **CLAUDE.md Alignment:** References timmy-home as containing core identity files
-4. **Separation of Concerns:**
