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
