chore(release): 0.27.0-fork.31 — Web Store submission ready + two install paths

- extension: popup status page (paired/not-paired) so the listing has standalone
  UI; renamed agent-browser-stealth + new icon (earlier in this line)
- store: upload zip strips manifest "key" (the Web Store forbids it); the unpacked
  dir + .crx keep it. Submitted for review (item knfcmbamhjmaonkfnjhldjedeobeafmk).
- connect: native-messaging allowed_origins lists BOTH the local Load-unpacked id
  (ciiljdlhd…) and the store-assigned id (knfc…), so either install path pairs.
- ci: launch-based jobs opt into AGENT_BROWSER_ALLOW_HEADLESS for display-less
  runners (fixes Native E2E); + version-sync/dashboard/fmt/clippy/flaky-test repairs.
- docs: skill documents both install methods (Load unpacked now, Web Store later).

 Stealth fork of [agent-browser](https://github.com/vercel-labs/agent-browser) — connects to your real Chrome, shares your login sessions, and is undetectable by anti-bot systems.
 
 For basic usage, commands, and API reference, see the [upstream documentation](https://github.com/vercel-labs/agent-browser).
 
 ## Why this fork?
 
+<img src="assets/fingerprint.png" alt="real but undetectable fingerprint" width="300" align="right" />
+
 **agent-browser** launches a fresh browser with an empty profile. You need to log in again, and websites can detect it's automated.
 
 **agent-browser-stealth** connects to your existing Chrome. Your cookies, sessions, and browser fingerprint are all real — because it IS your real browser.

 When connected to your real Chrome, we inject **zero** JavaScript patches. Your browser's fingerprint is completely genuine. The guiding rule is **native CDP/Chrome overrides over JS lies** — a re-defined getter is itself detectable; a native override isn't.

-When using `--launch` mode (standalone browser), a full suite of 32 stealth patches is applied for headless Chrome.
+`0% stealth` on CreepJS is the key number: because the connect path patches **nothing**, there is no override for a lie-detector to catch. (Dashboards that read `navigator.languages` order or IP geolocation may show a soft "navigator"/"location" flag — that tracks *your real Chrome's* language list and network, not an automation tell.)
+
+When using `--launch` mode (standalone browser), a full suite of stealth patches is applied instead, and it still passes the suite above.
+
+### Verify it yourself
+
+Don't take our word for it — point your connected Chrome at the toughest public detectors and compare:
+
+- **[CreepJS](https://abrahamjuliot.github.io/creepjs/)** — the most thorough fingerprint / lie detector
+- **[bot.incolumitas.com](https://bot.incolumitas.com/)** — behavioral + fingerprint scoring with a public methodology
+- **[BrowserScan](https://www.browserscan.net/bot-detection)** — Webdriver / User-Agent / CDP / Navigator
+- **[bot.sannysoft.com](https://bot.sannysoft.com)** — the classic automation-marker checklist
+- **[pixelscan.net](https://pixelscan.net/)** · **[iphey.com](https://iphey.com/)** — consistency & identity
+
+We deliberately **don't ship our own bot detector** — the strongest, most honest benchmark is the market's best detectors run against your real browser.
