feat(cloakserve): add connection tracking, configurable data dir, better status endpoint

- Move `import websockets` to top-level (guaranteed by [serve] extra)
- Add --data-dir flag with smart default (Docker → /tmp/cloakserve, bare metal → ~/.cloakbrowser/cloakserve)
- Store launch params (tz/locale/proxy) on ChromeProcess for conflict logging
- Enhance GET / to return per-process detail (pid, port, seed, connections, config)
- Add connection refcounting in WS handlers for status visibility
- Add first-launch-wins note to README
- Add tests for data-dir, Docker detection, and connection tracking

+- **[binary]** GPU fingerprint accuracy improvements — renderer suffix strings now match real Chrome output across Windows and Linux profiles
+- **[binary]** GPU capability accuracy fix for NVIDIA profiles — spoofed values now reflect actual hardware limits
+- **[binary]** macOS GPU accuracy fix — GPU model database reference corrected for Apple Silicon profiles
+- **[binary]** Fix CDP input synthesis — a guard condition prevented the patch from activating; now fires correctly on all input events

+- **`humanize=True`** — one flag makes all mouse, keyboard, and scroll interactions behave like a real user. Bézier curves, per-character typing, realistic scroll patterns. Two presets: `default` and `careful`
+- **CDP input behavior mimicking** — input events sent via CDP now produce the same signals as real user interactions. 4 source-level patches covering pointer, keyboard, and mouse behavior
+- **Native locale spoofing** — new C++ patch replaces detectable CDP-level locale emulation
+- **WebGPU fingerprint hardening** — adapter features, limits, and device ID spoofed for cross-API consistency
+- **42 fingerprint patches** (Linux x64) — all 4 platforms on Chromium 145
 - **Stealthy with zero flags** — binary auto-generates a random fingerprint seed at startup. No configuration required
-- **Full stealth audit** — every patch reviewed for detection vectors, multiple fixes shipped
-- **CDP hardening** — audited and patched known automation detection vectors
 - **Timezone & locale from proxy IP** — `launch(proxy="...", geoip=True)` auto-detects timezone and locale
-- **Playwright + Puppeteer from one package** — `import from 'cloakbrowser'` or `import from 'cloakbrowser/puppeteer'`. Same binary, your choice of API

 - **Source-level stealth** — C++ patches handle fingerprints (GPU, screen, UA, hardware reporting) at the binary level. No JavaScript injection, no config-level hacks. Most stealth tools only patch at the surface.
 - **Same behavior everywhere** — works identically local, in Docker, and on VPS. No environment-specific patches or config needed.

+## Human Behavior
+
+Pass `humanize=True` to make all mouse, keyboard, and scroll interactions indistinguishable from real users. All Playwright calls — `page.click()`, `page.fill()`, `page.type()`, `page.mouse.*`, `page.keyboard.*`, and the full Locator API — are automatically replaced with human-like equivalents. No code changes needed.
+
+```python
+browser = launch(humanize=True)
+page = browser.new_page()
+page.goto("https://example.com")
+page.locator("#email").fill("user@example.com")  # per-character timing, thinking pauses
+page.locator("button[type=submit]").click()       # Bézier curve, realistic aim point
+```
+
+```javascript
+const browser = await launch({ humanize: true });
+```
+
+**What changes:**
+
+| Interaction | Default | With `humanize=True` |
+|---|---|---|
+| Mouse movement | Instant teleport | Bézier curve with easing and slight overshoot |
+| Clicks | Instant | Realistic aim point + hold duration |
+| Keyboard | Instant fill | Per-character timing, thinking pauses, occasional typos with self-correction |
+| Scroll | Jump | Accelerate → cruise → decelerate micro-steps |
+| `fill()` | Instant value set | Clears existing content, types character by character |
+
+**Presets** — `default` (normal speed) or `careful` (slower, more deliberate, idle micro-movements between actions):
+
+```python
+browser = launch(humanize=True, human_preset="careful")
+```
+
+```javascript
+const browser = await launch({ humanize: true, humanPreset: 'careful' });
+```
+
+**Custom config** — override any parameter:
+
+```python
+browser = launch(humanize=True, human_config={
+    "mistype_chance": 0.05,              # 5% typo rate with self-correction
+    "typing_delay": 100,                 # slower typing (ms per character)
+    "idle_between_actions": True,        # micro-movements between clicks
+    "idle_between_duration": [0.3, 0.8], # idle duration range (seconds)
+})
+```
+
+```javascript
+const browser = await launch({
+    humanize: true,
+    humanConfig: {
+        mistype_chance: 0.05,
+        typing_delay: 100,
+        idle_between_actions: true,
+        idle_between_duration: [0.3, 0.8],
+    }
+});
+```
+
+Access the original un-patched Playwright page at `page._original` if you need raw speed for a specific call.
+
+> **Note:** Always use `page.click(selector)`, `page.type(selector, text)`, `page.hover(selector)`, or `page.locator(selector).*` — these go through the full humanize pipeline. Avoid `page.query_selector()` — `ElementHandle` objects bypass all patches, so mouse movement teleports, keyboard events fire without timing, and scroll has no human curve.

-"""Launch stealth Chromium as a CDP server for remote connections.
+"""CDP multiplexer — per-connection fingerprint seeds for stealth Chromium.
+
+Spawns a separate Chrome process per unique fingerprint seed, routing CDP
+connections through a single port. Each seed gets its own browser identity.
 
 Usage:
-    cloakserve                          # headless on port 9222
-    cloakserve --headless=false         # headed (uses Xvfb in Docker)
-    cloakserve --proxy-server=host:port # with proxy
+    cloakserve                                      # default, backward compat
+    cloakserve --port=9222                           # custom port
 
-Connect from host:
-    playwright.chromium.connect_over_cdp("http://localhost:9222")
+Client:
+    browser = pw.chromium.connect_over_cdp("http://host:9222?fingerprint=12345")
+    browser = pw.chromium.connect_over_cdp(
+        "http://host:9222?fingerprint=12345&timezone=America/New_York&locale=en-US"
