chore(release): 0.27.0-fork.29 — plugin overflowTest fix, popup-free auto-connect, ab-connect rebrand+icon, README

- stealth(plugins): stop overwriting real native navigator.plugins in headed
  mode (the JS fake had a non-native item(), broken uint32 wrap → incolumitas
  overflowTest FAIL, and an anachronistic Native Client plugin). Leave native
  plugins untouched when present; modernize the headless-escape fallback to the
  real 5 PDF-viewer set with masked-native item()/namedItem().
- connect: auto_connect_cdp() now prefers the dialog-free ab-connect relay over
  the raw :9222 CDP port, so Chrome 136+'s "Allow remote debugging?" consent
  modal no longer fires when the extension relay is live. Gated by a bare-TCP
  relay_is_live() probe (+3 unit tests).
- extension: rename ab-connect to "agent-browser-stealth" + new stealth icon set
  (16/32/48/128).
- docs(README): hero/shield/fingerprint images, expanded detector results
  (CreepJS 0% stealth, incolumitas all-OK, BrowserScan CDP-clean), and a
  "Verify it yourself" section. .gitignore: allow assets/ + extension icons.
