docs: add recommended config to quick-start, FPJS troubleshooting, update contributors

- Add production-ready snippet (proxy, geoip, headless, humanize) near top of both READMEs
- Add "Detected by FingerprintJS?" troubleshooting with verified flags:
  noise=false, screen dimensions, storage quota, geoip, residential proxy
- Add @sparanoid to contributors (Docker Xvfb lock fix)
- Update @eofreternal credit (iframe pointer-events fix)
- Fix stale "48 patches" in JS README

+### Detected by FingerprintJS?
+
+FingerprintJS (`demo.fingerprint.com/playground`) checks multiple signals. Each detection has a specific cause:
+
+| Detection | Cause | Fix |
+|-----------|-------|-----|
+| **`nodriver` / bad bot** | IP reputation or missing flags | Residential proxy + config below |
+| **Browser tampering** | Noise injection detected by ML | `--fingerprint-noise=false` |
+| **Virtual machine** | Screen dimensions don't match viewport | `--fingerprint-screen-width/height` matching viewport |
+| **Incognito** | Storage quota normalized to ~500MB | Expected tradeoff — see below |
+
+Config that passes FPJS (verified on v0.3.30, Linux + Windows):
+
+```python
+browser = launch(
+    headless=False,
+    proxy="http://user:pass@residential-proxy:port",
+    geoip=True,
+    args=[
+        "--fingerprint-noise=false",          # prevents tampering detection
+        "--fingerprint-screen-width=1920",    # match your viewport
+        "--fingerprint-screen-height=1080",
+    ],
+)
+```
+
+```javascript
+const browser = await launch({
+    headless: false,
+    proxy: 'http://user:pass@residential-proxy:port',
+    geoip: true,
+    args: [
+        '--fingerprint-noise=false',
+        '--fingerprint-screen-width=1920',
+        '--fingerprint-screen-height=1080',
+    ],
+});
+```
+
+For persistent contexts (`launch_persistent_context` / `launchPersistentContext`), also add `--fingerprint-storage-quota=500` to the args.
+
+**Storage quota tradeoff:** The binary normalizes storage quota to ~500MB to pass FPJS, but this makes the session look like incognito to other detection services (e.g. BrowserScan's `notPrivate` check, -10 points). Setting `--fingerprint-storage-quota=5000` passes incognito checks but may trigger FPJS. You can't satisfy both simultaneously — choose based on what your target site checks. See the [storage quota tradeoff table](#launch_persistent_context) for details.

 ### Blocked on Kasada / Akamai sites despite correct config?
 
 On minimal Linux environments, missing font packages cause canvas emoji rendering to produce hashes that anti-bot systems don't recognize. This is the most common cause of blocks on aggressive sites after proxy, geoip, and headed mode are already set up correctly.
