Add VPN configuration tools and agent documentation

Created comprehensive VPN setup tooling for Peaceful Spirit L2TP/IPsec connection
and enhanced agent documentation framework.

VPN Configuration (PST-NW-VPN):
- Setup-PST-L2TP-VPN.ps1: Automated L2TP/IPsec setup with split-tunnel and DNS
- Connect-PST-VPN.ps1: Connection helper with PPP adapter detection, DNS (192.168.0.2), and route config (192.168.0.0/24)
- Connect-PST-VPN-Standalone.ps1: Self-contained connection script for remote deployment
- Fix-PST-VPN-Auth.ps1: Authentication troubleshooting for CHAP/MSChapv2
- Diagnose-VPN-Interface.ps1: Comprehensive VPN interface and routing diagnostic
- Quick-Test-VPN.ps1: Fast connectivity verification (DNS/router/routes)
- Add-PST-VPN-Route-Manual.ps1: Manual route configuration helper
- vpn-connect.bat, vpn-disconnect.bat: Simple batch file shortcuts
- OpenVPN config files (Windows-compatible, abandoned for L2TP)

Key VPN Implementation Details:
- L2TP creates PPP adapter with connection name as interface description
- UniFi auto-configures DNS (192.168.0.2) but requires manual route to 192.168.0.0/24
- Split-tunnel enabled (only remote traffic through VPN)
- All-user connection for pre-login auto-connect via scheduled task
- Authentication: CHAP + MSChapv2 for UniFi compatibility

Agent Documentation:
- AGENT_QUICK_REFERENCE.md: Quick reference for all specialized agents
- documentation-squire.md: Documentation and task management specialist agent
- Updated all agent markdown files with standardized formatting

Project Organization:
- Moved conversation logs to dedicated directories (guru-connect-conversation-logs, guru-rmm-conversation-logs)
- Cleaned up old session JSONL files from projects/msp-tools/
- Added guru-connect infrastructure (agent, dashboard, proto, scripts, .gitea workflows)
- Added guru-rmm server components and deployment configs

Technical Notes:
- VPN IP pool: 192.168.4.x (client gets 192.168.4.6)
- Remote network: 192.168.0.0/24 (router at 192.168.0.10)
- PSK: rrClvnmUeXEFo90Ol+z7tfsAZHeSK6w7
- Credentials: pst-admin / 24Hearts$

Files: 15 VPN scripts, 2 agent docs, conversation log reorganization,
guru-connect/guru-rmm infrastructure additions
