feat(connect): force-install ab-connect via Chrome config profile (no Load-unpacked GUI)

Chrome 149 killed every GUI-free way to load an *unpacked* extension into the
real profile: --load-extension removed in Chrome 142 (incl. the
--disable-features workaround), local-.crx external install blocked on macOS
since Chrome 44, remote-debugging-port killed in Chrome 136. So agents were
stuck automating the chrome://extensions Load-unpacked native file dialog —
unworkable.

`extension install` now writes a macOS configuration profile that force-installs
the signed .crx from a hosted update_url (ExtensionInstallForcelist policy). One
approval in System Settings (a single fixed Install button — cua-driver-friendly,
unlike a file dialog) → Chrome force-installs + auto-updates the extension on next
launch. No token, no per-use confirmation, and binary-install users no longer
need the extensions/ folder (crx is fetched from the URL).

- pin a stable signing key; new extension id ciiljdlhdpfckdcfkphgmfalanpdejep
- ship signed extensions/ab-connect.crx + extensions/updates.xml (raw GH host)
- scripts/pack-extension.sh re-signs with the stable key; .secrets/*.pem ignored
- uninstall removes the profile file + prints `profiles remove` hint
