fix: sync wrapper with v11-v13 binary changes

- Rename --timezone to --fingerprint-timezone (breaking binary change in v13) - Remove --fingerprint-taskbar-height from defaults (binary auto-applies per platform) - Update viewport height 955→947 (48px Win taskbar default) - Update patch count 26→25 (patch 003 deleted in v11) - Document new flags: --fingerprint-fonts-dir, --enable-blink-features=FakeShadowRoot, --fingerprint-taskbar-height (optional override) - Fix README: remove incorrect "defaults to windows" claim

 ## Fingerprint Management

-The binary is **stealthy by default** — no flags needed. It auto-generates a random fingerprint seed at startup and spoofs all detectable values (GPU, hardware specs, screen dimensions, canvas, WebGL, audio, fonts). Every launch produces a fresh, coherent identity.
-
-**How fingerprinting works:**
-
-| Scenario | What happens |
-|----------|-------------|
-| **No flags** | Random seed auto-generated at startup. GPU, screen, hardware specs, and all noise patches are spoofed automatically. Fresh identity each launch. |
-| **`--fingerprint=seed`** | Deterministic identity from the seed. Same seed = same fingerprint across launches. Use this for session persistence (returning visitor). |
-| **`--fingerprint=seed` + explicit flags** | Explicit flags override individual auto-generated values. The seed fills in everything else. |
-
-The binary detects its platform at compile time — a macOS binary reports as macOS with Apple GPU, a Linux binary reports as Linux with NVIDIA GPU. The **wrapper** overrides this on Linux by passing `--fingerprint-platform=windows`, so sessions appear as Windows desktops (more common fingerprint, harder to cluster). Use `--fingerprint-platform` for cross-platform spoofing when running the binary directly.
+Every launch automatically generates a **unique fingerprint**. A random seed (10000–99999) drives all seed-based patches — canvas, WebGL, audio, fonts, and client rects all produce consistent, correlated values derived from that single seed.

 > **Tip: Use a fixed seed when revisiting the same site.** A random seed makes every session look like a different device — which can be suspicious when hitting the same site repeatedly from the same IP. For reCAPTCHA v3 Enterprise and similar scoring systems, a fixed seed produces a consistent fingerprint across sessions, making you look like a returning visitor:

-The binary auto-generates hardware concurrency (8), device memory (8), and screen dimensions (1920x1080 on Windows/Linux, 1440x900 on macOS) from the seed. Override with explicit flags if needed.
-
-> **Using the binary directly?** It works out of the box with zero flags — the binary auto-spoofs everything. Pass `--fingerprint=seed` for a persistent identity, or use explicit flags like `--fingerprint-gpu-renderer` to override any auto-generated value.
-
-> **Production tip:** For better stealth at scale, pass your own GPU, screen, and hardware values instead of relying on defaults. Custom parameters make your sessions harder to cluster by anti-bot systems that look for uniform fingerprint profiles.
+> **Important:** `--fingerprint-platform` should always be set. Without it, platform-specific patches (GPU, UA, screen, taskbar) won't activate. The wrapper handles this automatically.

 ## Troubleshooting

-**Site detects incognito / private browsing mode**
-
-By default, `launch()` opens an incognito context. Some sites (like BrowserScan) detect this. Use `launchPersistentContext()` instead — it runs with a real user profile:
-
-```javascript
-import { launchPersistentContext } from 'cloakbrowser';
-
-const ctx = await launchPersistentContext({
-  userDataDir: './my-profile',
-  headless: false,
-});
-```
-
-This also gives you cookie and localStorage persistence across sessions.

 **reCAPTCHA v3 scores are low (0.1–0.3)**

 Avoid `page.waitForTimeout()` — it sends CDP protocol commands that reCAPTCHA detects. Use native sleep instead:
