v0.3.0 Beta Release

[0.3.0-beta] - 2025-09-10

✨ Features

• Added meter modes: Live, Peak, Hold, None — freeze or follow peaks just like a true peak meter.
• CW-friendly polling with tunable intervals, reducing PTT delay in CW operation.
• Automatic serial reconnect when the Mercury LUX amplifier is powered back on (no user interaction required).
• Improved On-Air notification styling (bold white on red, fixed size).
• Hide/show meter ticks and tick labels for a cleaner or more detailed display.
• Alarm codes mapped to friendly names from the user manual for easier troubleshooting.
• Added EMA smoothing option for meter updates, improving readability of fast-changing signals.

🛠 Improvements

• Cadence-based updates to PowerBar text and bar values, making SSB and CW signals easier to follow.
• Tick labels now color-coded (green/yellow/red) according to thresholds.
• Peak marker decay scales with meter range for consistent responsiveness across meters.
• App Scale Factor now properly persists after Save and restart.
• Light theme readability improvements (green/yellow text fixed).
• TLS certificate generation handling improved — clearer errors if OpenSSL or config missing.

🐞 Fixes

• Fixed black window issue when restoring from “Show Desktop” on Windows.
• Fixed TLS errors when OpenSSL was not found or config file missing.
• Fixed tick label overlap/cutoff (e.g., at 1800 W).
• Fixed bar/value disappearing in None meter mode.
• Fixed App Scale Factor reset bug after Save.
• Fixed client app showing stale meter values when server was closed — meters now clear and state updates immediately.
