⚠️ Pre-release ⚠️

Incremental changes since v.2.5.0-beta0

Noise Cancellation panel (side-menu entry): software microphone noise suppression via a LADSPA plugin chain.
Five presets: Off, Light (HPF + RNNoise), Standard (+ noise gate), Studio (+ compressor), Custom (full manual control). Default: Standard.
Custom mode exposes gate parameters (threshold, reduction, attack, release) and compressor parameters (threshold, ratio, makeup gain), each with a per-section reset-to-defaults button.
Input device selector, defaulting to the detected Arctis microphone source.
Runtime plugin detection: missing ladspa-rnnoise-plugin disables the whole panel with a banner and per-distro install instructions; missing swh-plugins disables only HPF/gate/compressor stages with a separate inline banner. Both banners include a Retry button.
D-Bus NC interface stub (GetNCCapabilities, GetNCSettings, SetNCSettings) on /NC object path — daemon-side implementation is a separate task.
