Subject: [PATCH] Simplify grep pattern in is_pkg_installed() for safer opkg
 matching (#117)

* Fix is_pkg_installed() opkg detection: use list-installed + exact grep match

opkg status always returns exit code 0 regardless of whether the package
is installed, making the previous check unreliable. Replace with
opkg list-installed piped through grep -q with an anchored pattern to
ensure exact package name matching without partial matches.
