feat: add advanced dpkg/apt lock fixer script for Termux (#6)

* Add French translation and fix STATE_FILE in explain.sh

* feat: add advanced dpkg/apt lock fixer script for Termux

Description
On some Termux environments (especially non-rooted recent Android versions like Android 13/14 on Xiaomi/Redmi devices), the standard tdoc fix routine might fail to completely release or detect stale dpkg or apt frontend locks.
This script provides a safe, automated, and strict fallback method:
It checks if an actual apt or dpkg process is running to prevent breaking active installations.
If no active PID is found, it forcefully removes the standard orphan lock files (lock, lock-frontend, etc.).
It triggers a final verification via tdoc doctor.

Environment tested:
Termux 0.118.3
Device: Xiaomi Redmi Note 13 Pro+ 5G (Android 13 / SDK 33, non-rooted)
Feel free to integrate this logic into the main core or keep it as a standalone helper script (tdocfix.sh).

* Fix dependabot labels
