add Java JDK/JRE selection and patches

- Created dedicated `extras/java.sh` module for modular Temurin/Adoptium repository handling and isolated GPG key management.
- Implemented selective JRE/JDK installation paths: Gaming (Minecraft) vs Development environments with version control selectors.
- Enhanced user group membership logic (`_ensure_sudo_group`) to auto-configure administrative privileges on fresh installs.
- Introduced maintenance-friendly passwordless sudo for `apt`, `systemctl`, and shutdown commands via `/etc/sudoers.d/`.
- Added home directory ownership repair utility to fix root-owned files in user directories after improper `sudo` usage.
- Enabled visual password feedback (`pwfeedback`) toggle for enhanced terminal usability during authentication prompts.
- Refactored Debian 13/Trixie repository sourcing logic to ensure idempotency and prevent backports/duplicate sources conflicts.
- Updated Bullseye legacy modules (extras.sh, repos.sh) to exclude deprecated packages (`hx`, `vscodium`) and enforce Firefox ESR defaults.
- Cleaned repository configurations by removing obsolete `bullseye-updates` source entries to prevent dependency conflicts.
- Implemented NVTOP conditional detection logic ensuring display only on active Nvidia drivers or supported architectures (Trixie/Bookworm).
- Corrected `/modules/bullseye/extras.sh` menu mappings (Programming, Dev Tools) and verified package lists excluding incompatible tools (`hx`, `vscodium`).
- Integrated ClamAV security module with daemon state management and background scan execution flows in all Security menus.
- update README.md

+## User Privileges & Feedback
+
+Admin rights, passwordless commands, and file ownership fixes—optimized for Debian users.
+
+### 1. Sudo Group Membership
+If you just installed Debian and can’t install software or change system settings (you get "Permission denied"), this option adds your user to the sudo group. This gives you admin privileges so you can manage your system. Changes take effect after you log out and back in.
+
+### 2. Passwordless Sudo for Frequent Tasks
+Every time you run sudo apt install or sudo reboot, Linux asks for your password. This option lets you skip typing your password for common commands like installing/updating software (apt), restarting or shutting down (systemctl).
+- ⚠️ Security Note: While convenient, this reduces security if someone else uses your PC physically.
+
+### 3. Repair Home Directory Ownership
+Sometimes, when you use sudo incorrectly (e.g., installing games or apps), files get "stolen" by the system (root) instead of your user. This causes apps to fail (e.g., saving settings or game progress). This option fixes ownership so all your files and folders belong to you again.
+
+### 4. Sudo Password Feedback (Asterisks)
+By default, Debian’s terminal hides your password (no asterisks or feedback). This option adds visual feedback (e.g., ****) so you can see how many characters you’ve typed. Toggle it on/off as needed.
