feat(connect): install + recognize BOTH native-messaging host names (staged extension migration)

Stage 1 of the agent-browser → chrome-use extension migration: the CLI now
writes a host manifest under both com.agent_browser.connect (extension ≤0.4.2)
AND com.leeguoo.chrome_use (the rebrand 0.5.0+), both pointing at the same
launcher, and host_installed()/uninstall recognize both. So the relay works no
matter which extension version a user has, with no forced re-install — which
lets the store roll 0.4.3 (cosmetic name only, host unchanged) and later 0.5.0
(new host) without ever breaking the relay or re-popping the consent dialog.
