Integrate Proxmox host optimization into one-button optimizer

Browse Source 
Major changes:
- Added Proxmox detection with interactive mode selection
- Mode 1: Proxmox Host (hypervisor-optimized)
  - Different kernel parameters (swappiness=10, BBR, FQ)
  - Minimal tmpfs (2GB APT cache only)
  - No zram (VMs need direct RAM)
  - No desktop app configuration
- Mode 2: Desktop (original behavior with warnings)
- Mode 3: Abort (recommends running in VMs)

Technical implementation:
- check_proxmox() now offers mode selection
- analyze_and_prompt() branches on PROXMOX_MODE
- tune_kernel() handles both desktop and proxmox profiles
- setup_tmpfs() handles minimal proxmox tmpfs
- Updated PROXMOX_COMPATIBILITY.md with new behavior

Result: One unified script for both desktop and Proxmox use cases

# Proxmox Host Compatibility Analysis
## ⚠️ Running on Proxmox Host: Safety Considerations
## ✅ **NEW: Integrated Proxmox Support!**
### 🔴 **NOT RECOMMENDED for Proxmox Host**
The one-button optimizer now **automatically detects** Proxmox hosts and offers **two modes**:
This toolkit is designed for **Linux desktop systems** and **should NOT be used on a Proxmox host** without modifications. Here's why:
```bash
sudo ./one-button-optimizer.sh
```
### When run on Proxmox host, you'll see:
```
⚠️ Proxmox VE host detected!
<EFBFBD>️ System: Proxmox VE (5 VMs, 2 containers)
This tool has TWO modes:
1️⃣ Proxmox Host Mode (Hypervisor Optimization)
• Optimized kernel params for VM workloads
• Minimal RAM allocation (2GB for APT cache only)
• CPU performance governor
• Network optimization (BBR, FQ)
• No desktop app configuration
2️⃣ Desktop Mode (NOT recommended for host)
• Heavy RAM usage (zram + tmpfs = 40-50%)
• Desktop-focused optimizations
• Will reduce memory available for VMs
3️⃣ Abort (Recommended: Run inside your desktop VMs)
Choose mode (1=Proxmox/2=Desktop/3=Abort) [1]:
```
---
## ❌ Potential Issues on Proxmox Host
## 🎯 Proxmox Host Mode Optimizations
When you select **Mode 1 (Proxmox Host Mode)**, you get:
### 1. **Kernel Parameters**
```bash
vm.swappiness = 10 # Allow some swap (not aggressive like desktop)
vm.dirty_ratio = 10 # Handle VM write bursts
vm.dirty_background_ratio = 5 # Start background writes earlier
vm.vfs_cache_pressure = 50 # Balance inode/dentry cache
vm.min_free_kbytes = 67584 # Keep minimum free RAM
# Networking (optimized for VM/CT traffic)
net.core.default_qdisc = fq # Fair Queue
net.ipv4.tcp_congestion_control = bbr # Better bandwidth
net.core.netdev_max_backlog = 5000
net.ipv4.tcp_max_syn_backlog = 8192
```
### 2. **Minimal tmpfs (Optional)**
- Only 2GB for APT package cache
- Minimal RAM impact
- Speeds up `apt upgrade` operations
### 3. **No zram**
- Skipped entirely in Proxmox mode
- VMs need direct RAM access
### 4. **No Desktop Apps**
- Skips browser/IDE configuration
- Focus on hypervisor performance
---
## ❌ What's NOT Safe (Still Applies if You Choose Mode 2)
If you mistakenly choose **Desktop Mode** on Proxmox host:
### 1. **zram Configuration**
- **Issue**: Creates compressed swap in RAM
