refactor: reorganize flake structure and consolidate user config

Directory structure:
- Move from src/ to root level (system/, user/)
- Remove unused machines (workstation, vm, laptop)

User configuration:
- Add user/home.nix for shared defaults (pass, essentials, default modules)
- Centralize user options in user/default.nix
- Move submodules to consistent paths (bash/bash, git/git, neovim/nvim, vim/vim)

Module reorganization:
- Flatten nested module structures (remove /modules/ subdirs)
- Split CLI vs GUI tools (dev/ for CLI, gui/dev/ for GUI)
- Move neovim/vim to top-level modules (not under utils/)
- Remove security.enable - pass now in user/home.nix
- Remove utils.enable - essentials now in user/home.nix
- Add security/yubikey module with yubikey-manager, age-plugin-yubikey
- Move pcb, design to gui/dev/
- Replace penpot docker wrapper with nixpkgs penpot-desktop
- Remove i3 config
- Remove deprecated wsl.nativeSystemd option

GUI improvements:
- Browser-focused mimeApps in gui/default.nix
- Each WM handles its own auto-start via profileExtra

Cleanup:
- Update README with new structure
- Update justfile paths and valid systems
- Fix submodule paths in .gitmodules

+# Frigate Camera Setup
+
+## Camera Models
+
+| Camera | Model | MAC | IP |
+|--------|-------|-----|-----|
+| parking_lot | W461ASC | 00:1f:54:c2:d1:b1 | 192.168.1.194 |
+| doorbell | B463AJ | 00:1f:54:a9:81:d1 | 192.168.1.167 |
+| living_room | W463AQ (ch1) | 00:1f:54:b2:9b:1d | 192.168.1.147 |
+| kitchen | W463AQ (ch2) | 00:1f:54:b2:9b:1d | 192.168.1.147 |
+| porch | SL300 | | | |
+
+## Network Architecture
+
+- Camera network: 192.168.1.0/24 (isolated, no internet)
+- Server NIC: enp2s0f1 @ 192.168.1.1
+- WiFi AP: TP-Link RE315 @ 192.168.1.254
+- DHCP range: 192.168.1.100-200
+
+## RTSP URL Format
+
+```
+rtsp://admin:ocu?u3Su@<IP>/cam/realmonitor?channel=<CH>&subtype=0
+```
+
+- channel=1 for single-camera devices
+- channel=1,2 for dual-camera devices (W463AQ)
+- subtype=0 for main stream, subtype=1 for sub stream
+
+## Camera Reset Procedures
+
+### W461ASC (parking_lot)
+1. Keep camera powered on
+2. Reset button is on the back of the camera
+3. Press and hold reset button for 30-60 seconds until chime sounds
+
+### B463AJ (doorbell)
+1. Remove doorbell from mount
+2. Locate reset button on the back
+3. Press and hold until you hear chime reset sound
+4. Reconnect via Lorex app as new device
+
+### W463AQ (living_room/kitchen)
+1. Keep camera powered on
+2. Rotate the lens upwards to reveal hidden reset button
+3. Press and hold reset button until you hear audio prompt
+4. Flashing green Smart Security Lighting confirms reset
+5. Solid green = not fully reset, repeat if needed
+
+### SL300 (porch)
+1. Keep camera powered on
+2. Tilt camera lens upwards to reveal reset/microSD card cover
+3. Remove the cover
+4. Press and hold reset button until audio prompt
+5. Replace cover quickly
+6. Wait for green LED flash + audio confirmation
+
+## Initial Setup
+
+1. Temporarily enable internet for camera network:
+   ```bash
+   sudo iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o enp2s0f0 -j MASQUERADE
+   sudo sysctl -w net.ipv4.ip_forward=1
+   ```
+
+2. Connect camera to "cams" WiFi network
+
+3. Use Lorex app to configure camera (requires cloud - CCP middleman)
+
+4. Get camera MAC from DHCP leases:
+   ```bash
+   cat /var/lib/dnsmasq/dnsmasq.leases
+   ```
+
+5. Add DHCP reservation in `system.nix`:
+   ```nix
+   dhcp-host = [
+     "aa:bb:cc:dd:ee:ff,192.168.1.XXX,camera_name"
+   ];
+   ```
+
+6. Add MAC to firewall block list in `system.nix`:
+   ```nix
+   iptables -A FORWARD -m mac --mac-source aa:bb:cc:dd:ee:ff -j DROP
+   ```
+
+7. Update camera IP in `frigate/default.nix` and enable
+
+8. Deploy and disable internet:
+   ```bash
+   nixos-rebuild switch --flake .#server --target-host server
+   sudo iptables -t nat -D POSTROUTING -s 192.168.1.0/24 -o enp2s0f0 -j MASQUERADE
+   sudo sysctl -w net.ipv4.ip_forward=0
+   ```
+
+## Storage
+
+Frigate data is stored on /data to avoid filling root partition:
+
+| Path | Bind Mount | Contents |
+|------|------------|----------|
+| /var/lib/frigate | /data/frigate/lib | Database, recordings, clips |
+| /var/cache/frigate | /data/frigate/cache | Temporary cache |
+| /var/cache/nginx/frigate | /data/frigate/nginx-cache | API response cache |
+
+## Notes
+
+- Lorex cameras are cloud-only for configuration (no local web UI responds)
+- RTSP works locally without internet
+- Cameras phone home aggressively when internet is available - keep isolated
+- Haswell CPU cannot hardware decode HEVC - using CPU decode
+- Consider T400 GPU for hardware acceleration if scaling to more cameras
+
+## Port Scan Results (W461ASC)
+
+- 80/tcp - HTTP (non-responsive, proprietary)
+- 554/tcp - RTSP (working)
+- 8086/tcp - Proprietary
+- 35000/tcp - Proprietary
