Add BuddAI local launcher script and ngrok integration

- Introduced `run_buddai.ps1` to automate the setup and launch of the BuddAI server.
- Implemented checks for Docker and Ollama services, ensuring they are running before starting the server.
- Added model verification and automatic pulling of required AI models.
- Created a Python virtual environment and installed necessary dependencies.
- Configured firewall rules for port 8000 and provided options for remote access via ngrok or Tailscale.
- Enhanced user experience with informative messages and QR code generation for easy access to the server.
- Included logic to determine the best public URL for the server based on available network configurations.

+# Remote Access Implementation Log
+
+This document records the troubleshooting steps, failures, and solutions implemented to enable remote access (Ngrok & Tailscale) for the BuddAI system.
+
+## 1. Ngrok Execution Failures
+
+### Fail: "The term '.\ngrok' is not recognized"
+
+**Cause:** The script assumed `ngrok.exe` was in the current folder, but it wasn't, or it wasn't in the system PATH.
+**Fix:** Updated `run_buddai.ps1` to check both the global PATH (`ngrok`) and the local folder (`.\ngrok.exe`).
+
+### Fail: "Start-Process : The system cannot find the file specified"
+
+**Cause:** PowerShell's `Start-Process` command failed when using a relative path like `.\ngrok.exe`.
+**Fix:** Implemented `Resolve-Path` to convert the relative path to an absolute path before execution.
+
+## 2. Tunnel Timing Issues
+
+### Fail: Empty URL returned
+
+**Cause:** The script attempted to fetch the public URL from the Ngrok API immediately after starting the process. The tunnel takes a few seconds to establish.
+**Fix:** Added a **retry loop** in PowerShell that polls `http://localhost:4040/api/tunnels` every second for up to 15 seconds.
+
+## 3. Dependency Issues
+
+### Fail: "ModuleNotFoundError: No module named 'PIL'"
+
+**Cause:** The `qrcode` library was added to generate QR codes, but it relies on `pillow` (PIL) for image generation, which was missing.
+**Fix:** Added `pillow` to `requirements.txt` and wrapped the import in `main.py` with a `try/except` block to prevent server crashes.
+
+### Fail: PowerShell Parsing Errors
+
+**Cause:** Complex one-liner Python commands inside PowerShell strings caused syntax errors (specifically with parentheses and quoting).
+**Fix:** Refactored the Python QR code generation call to be cleaner and safer within the script.
+
+## 4. Network & Firewall
+
+### Fail: "Run as Administrator to enable LAN/VPN access"
+
+**Cause:** Windows Firewall blocks incoming connections to port 8000 by default, preventing LAN and Tailscale access.
+**Fix:** Added automatic detection of the missing firewall rule. The script now prompts the user to press 'A' to restart as Administrator and applies the rule automatically using `New-NetFirewallRule`.
+
+### Fail: Tailscale IP Not Detected
+
+**Cause:** The script looked specifically for a network interface named "Tailscale", but on some systems, the adapter name differs.
+**Fix:** Added a fallback detection method that scans for any active IPv4 address in the `100.x.x.x` range (Carrier Grade NAT), which Tailscale uses.
+
+## 5. User Experience (UX) Friction
+
+### Fail: Annoying Ngrok Prompt
+
+**Cause:** Users with Tailscale (which is always on) were forced to wait 3 seconds or press a key to skip the Ngrok prompt every time.
+**Fix:** Added logic to **auto-detect Tailscale**. If a Tailscale IP is found, the script now automatically skips the Ngrok prompt and defaults to the private VPN URL.
+
+### Fail: "How do I view this on mobile?"
+
+**Cause:** Users had to manually type long IP addresses or URLs into their phone.
+**Fix:**
+
+1. Integrated a **QR Code Generator** directly into the Python backend (`/api/utils/qrcode`).
+2. Updated the root dashboard (`/`) to dynamically display the active IP (LAN, Tailscale, or Ngrok) and a scannable QR code.
+
+## Final Status
+
+The system now supports three robust access methods:
+
+1. **Local Network (LAN):** Auto-configured via Firewall rules.
+2. **Private VPN (Tailscale):** Auto-detected with priority handling.
+3. **Public Tunnel (Ngrok):** Optional fallback with secure/public modes.
