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).
