Description

Adds Arch Linux dependency installation instructions to README.md and updates scripts/install_deps.sh to auto-detect Arch Linux and install the required dependencies using pacman.

Latest Updates:

• Native PKGBUILD: Added a native Arch package script (arch/PKGBUILD) that cleanly handles dependencies, static OpenCV compilation, and configuration preservation (backup array).
• GitHub Actions CI Validation: Added an isolated build-arch-linux job to our CI pipeline. It builds the package in a clean archlinux:base-devel container to guarantee there are no undeclared dependencies.
• Dependency Fixes: Fixed the missing tpm2-tss package in pacman, correctly preserved libtss2-dev for Debian/Ubuntu environments, and updated scripts/build_opencv.sh to use pacman.

Fixes #73

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

• Verified correct syntax for Arch Linux pacman dependencies.
• Validated bash script syntax for OS detection.
• Tested PKGBUILD generation in a clean Arch container via GitHub Actions.

@yuragyura I've put together a PR with the Arch Linux build instructions and updated the script to handle pacman automatically as requested. Please take a look!

Dependencies list working fine. build_opencv.sh ends with error while tries to use apt-get
~/Загрузки/LinuxCamPAM-20a9c024eecb842d2cf776de7c511a9f55354a39 1m 20s ❯ ./scripts/build_opencv.sh === Building OpenCV 4.12.0 (Static) from Source === Target: /home/ca0/Загрузки/LinuxCamPAM-20a9c024eecb842d2cf776de7c511a9f55354a39/opencv_static Installing Dependencies... sudo: apt-get: команда не найдена

Hey, @yuragyura!
Sorry for the wait. I just pushed some massive updates to the feat/arch-linux-instructions branch to sort this out and I've overhauled the documentation.

I added a native PKGBUILD so you can build and install it the Arch way.

To test this specific PR, you'll need to modify the PKGBUILD slightly so it pulls this branch instead of master, and then follow the new manual PAM setup instructions:

git clone https://github.com/Vladush/LinuxCamPAM.git
cd LinuxCamPAM/arch

# Edit the PKGBUILD to point to this PR's branch
sed -i 's|source=("git+https://github.com/Vladush/LinuxCamPAM.git")|source=("git+https://github.com/Vladush/LinuxCamPAM.git#branch=feat/arch-linux-instructions")|' PKGBUILD

makepkg -si

After it installs, it will not automatically configure PAM (unlike the Debian installer). You'll need to follow the Arch Linux Post-Installation steps in the README to enable the service and add the pam_faillock rules safely.

Could you give it a quick spin when you have a chance? Let me know if it successfully unlocks your sudo and screen, and I'll get it merged.

Буду очень признателен за фидбек!
