- Create SplashView with animated VU meter icon, wave background
- Show "presented by GNAFZGI SOFTWARE" on app startup
- Auto-dismiss after 2.5 seconds with fade transition
- Bump version to 1.3
- Auto-probe now automatically connects after finding a VU meter
- Add connection status indicator (green/red dot) on each dial
- Add animation to dial value changes
- Show minimum arc value for better visibility at low values
- Display error messages in hardware panel
- Show "No USB serial devices" message when none found
- Improved status display with port name in green when connected
- Add TCP server (VUServer.swift) for external apps to send VU meter values
- Server supports VU Protocol (#channel:value), JSON, and raw bytes
- Configurable options: port, max clients, remote access, broadcast levels
- Add ServerView.swift with full server settings UI and client management
- Improve auto-probing to use two-phase detection (port scan then protocol test)

- Add network and serial entitlements for server and USB access
- Update version to 1.2.0
Features:
- Auto-probe scans all USB serial ports to find VU meter
- Tests multiple baud rates (115200, 9600, 57600, 38400, 19200)
- Tests all protocols (Raw, Text, JSON, VU-Server)
- Detects response from hardware to confirm connection
- Known USB device detection (CH340, CP210x, FTDI, Arduino, etc.)
- USB Vendor/Product ID display in port selection
- Quick Connect button for instant auto-connection
- Progress bar and status during probing
- Probe results display for debugging
USB detection:
- Reads USB idVendor/idProduct from IOKit registry
- Marks known VU meter devices with star icon
- Auto-selects detected VU meter port
New features:
- SerialManager for USB/Serial communication with hardware
- Support for 4 physical VU meter dials
- Flexible channel mapping: Audio L/R, Peak, Mono, CPU, RAM, Disk, Network

- Hardware settings sheet for configuration
- Auto-detection of USB serial devices
Protocol formats:
- Raw: [0xAA][D1][D2][D3][D4][0x55]
- Text: CH1:val;CH2:val;CH3:val;CH4:val\n
- JSON: {"dials":[d1,d2,d3,d4]}
- VU-Server: #0:val\n#1:val\n...
Features:
- Real-time audio level monitoring via BlackHole virtual audio device
