refactor: simplify stealth args — rely on binary auto-generation (v14+)

Binary v14+ auto-generates hardware concurrency, device memory, screen
dimensions, and window size from the fingerprint seed. Remove these
explicit flags from Python/JS wrapper defaults and update README:

- Remove 5 flags from get_default_stealth_args() in both wrappers
- Move hardware-concurrency, device-memory, screen-width, screen-height
  to the Additional Flags table with auto-generated defaults documented
- Update code examples to use --fingerprint instead of --window-size
- Simplify fingerprint defaults table to show only wrapper-set flags

-## [0.3.6] — 2026-03-04
-
-- **[wrapper]** `proxy` parameter now accepts a Playwright proxy dict (`{server, bypass, username, password}`) in addition to URL strings — enables bypass lists and separate auth fields (PR #24). **TS note:** type changed from `string` to `string | object` — code that assumed `proxy` is always a string may need a `typeof` narrowing check

-- **[wrapper]** Add `launch_persistent_context()` and `launch_persistent_context_async()` (Python) — persistent browser profiles with cookie/localStorage persistence across sessions, avoids incognito detection (thanks [@evelaa123](https://github.com/evelaa123), [@yahooguntu](https://github.com/yahooguntu) — PRs #22, #17)
-- **[wrapper]** Add `launchPersistentContext()` (JS/TS) — same feature for JavaScript with full type support

-Binary v14: auto-spoof restored with seed, wrapper simplified to match.
-
-- **[binary]** Restore full auto-spoof when `--fingerprint=seed` is set — all randomized properties now derive from the seed consistently
-- **[binary]** Auto-inject random fingerprint seed at startup if none provided. Binary is stealthy with zero flags
-- **[binary]** 26 source-level C++ patches (up from 25)
-- **[wrapper]** Simplify default stealth args — remove flags the binary now auto-generates. Wrapper still sets platform profile on Linux and `--no-sandbox`
-- **[wrapper]** Fix timezone in `launch_context()` — use Playwright's per-context timezone instead of binary flag, fixing mismatch when creating new browser contexts with geoip
-- **[wrapper]** Clarify README platform detection behavior

 ## [0.3.3] — 2026-03-03

-**macOS: Blocked on some sites that pass on Linux**
-
-The macOS fingerprint profile has known inconsistencies that aggressive bot detection catches. If a site blocks you on macOS but works on Linux, switch to a Windows fingerprint profile by passing `stealth_args=False` and manually setting `--fingerprint-platform=windows` with matching GPU flags (see [Fingerprint Management](#fingerprint-management) for the full flag list).
-
-**Site detects incognito / private browsing mode**
-
-By default, `launch()` opens an incognito context. Some sites (like BrowserScan) detect this. Use `launch_persistent_context()` instead — it runs with a real user profile, so incognito detection passes:
-
-```python
-from cloakbrowser import launch_persistent_context
-
-ctx = launch_persistent_context("./my-profile", headless=False)
-page = ctx.new_page()
-```
-
-```javascript
-import { launchPersistentContext } from 'cloakbrowser';
-
-const ctx = await launchPersistentContext({
-  userDataDir: './my-profile',
-  headless: false,
-});
-```
-
-This also gives you cookie and localStorage persistence across sessions.

 ## 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:
