CreepJS detects three things for webDriverIsOn:
1. Property deletion (navigator.webdriver === undefined)
2. Value check (!!navigator.webdriver)
3. Lie detection (descriptor tampering via lieProps)
Changed from delete/defineProperty-value approach to replacing the CDP
getter with a getter returning false, matching the native descriptor shape.
Note: 33% headless in CreepJS is a CDP-inherent signal (lieProps detects
the getter replacement). This cannot be eliminated at the JS layer since
CDP sets the webdriver getter before init scripts run. Real-world impact
is minimal — Cloudflare Turnstile passes successfully.
Also confirmed: Chrome's remote_debugging preference in Local State
persists across restarts, so users only need to enable CDP once via
chrome://inspect/#remote-debugging.

- CdpAttach mode: only removes navigator.webdriver (user's real Chrome
already has genuine fingerprint, heavy patches create detectable lies)
- FullLaunch mode: applies all 32 patches (new Chrome needs full coverage)
- Improved webdriver removal: uses Object.defineProperty to override CDP
getter on Navigator.prototype, not just delete
- CreepJS results: 0% stealth (was 20%), hasIframeProxy: gone

- Auto-connect is now ON by default (was opt-in via --auto-connect)
- Added --launch/--new flags to explicitly start a fresh browser
- CI environments (CI env var) automatically use --launch mode
- Friendly error message with platform-specific Chrome relaunch guide
- Mentions Chrome 144+ runtime CDP toggle (chrome://inspect)
- --cdp and --provider flags implicitly disable auto-connect
- AGENT_BROWSER_NO_AUTO_CONNECT=1 to disable, AGENT_BROWSER_FORCE_LAUNCH=1 to force
Track 3 of native-stealth migration.

- Created cli/src/native/stealth.rs with stealth JS injection via CDP
- Extracted 32 patch IIFEs from TS stealth.ts into stealth_scripts.js
- Injected via Page.addScriptToEvaluateOnNewDocument on every launch/connect
- Added stealth Chrome args (disable AutomationControlled, use ANGLE GL)
- Auto-detects and cleans HeadlessChrome from User-Agent string
- Overrides navigator.userAgentData high-entropy hints
- Stealth enabled by default, disable with AGENT_BROWSER_STEALTH=0
