stornic56 f0cea296d7 fix harden hardware detection D3cold freezes 
Fixes a critical startup crash on hybrid graphics laptops (e.g., Intel + Nvidia) running fresh Debian installs without proprietary drivers. 

When the secondary GPU enters D3cold power state, kernel-level I/O operations (like `lspci` or reading `/sys/block/`) hang in Uninterruptible Sleep (State D), ignoring standard kill signals and freezing the terminal. Combined with `set -euo pipefail`, these hangs made the script silently fail or enter infinite loops.

Changes:
- Timeout Wrappers: Wrapped all hardware probing commands (`lspci`, `lsblk`, `cat /sys/...`, `ip`, `iwgetid`, `pw-cli`) with `timeout 2` to force-continue if the kernel blocks.
- Pipeline Safety: Added `|| true` to `nvidia-smi` and `dpkg` fallback queries to prevent `pipefail` from killing the script when drivers are missing.
- Loop Hardening: Fixed an infinite loop in `detect_gpu()` where empty `lspci` outputs caused by timeouts would loop forever by adding `[[ -z "$line" ]] && continue`.
- TUI Fallbacks: Added default values for `${LINES:-24}` and `${COLUMNS:-80}` to prevent `set -u` from crashing the `whiptail` menu in restricted shell environments.

stornic56 cd965a6678 bash gpu detection fix & nvidia-smi hardening 
- Fixed critical script termination on hybrid GPU systems (Intel+Nvidia). The `set -euo pipefail` header was causing immediate exit when `read` reached EOF with exit code 1, preventing further execution despite valid hardware detection.
- Added `|| true` to the lspci processing loop in `modules/utils.sh`. This forces the while read condition to always return success (0), allowing clean loop termination and proper variable assignment for `HAS_NVIDIA=true` and `HAS_INTEL=true`.
- Hardened nvidia-smi driver version query with timeout protection. Wrapped the command call with `|| true` to capture exit code 124 from `timeout`, preventing script abortion when GPU enters D3cold state or command fails.
- Changes applied at line 204 (while read loop) and line 243 (nvidia-smi query). Both modifications ensure the main script continues execution after hardware detection completes, enabling full menu loading on dual-GPU laptops.
