PlasmaZones v1.12.2

Audio visualizer: CAVA process silently failed when bar count was odd (exit code 1, "must have even number of bars with stereo output"). Even bar counts are now enforced at all layers: CavaService, KCM setter, and UI slider (stepSize=2).
Audio shader data: QML || [] fallback on audioSpectrum binding forced V4 JavaScript conversion, losing the native QVector<float> type needed by ZoneShaderItem's fast path. Replaced with a Binding element guarded by when to preserve type identity through the binding chain.
CAVA stderr capture: Switched from ForwardedErrorChannel to SeparateChannels so CAVA error output is captured in daemon logs instead of lost.
CAVA exit diagnostics: Moved exitCode()/readAllStandardError() from stateChanged to finished signal handler per Qt API contract. Only warns on non-zero exit code (stderr on exit 0 is normal for CAVA).

Shared audio constants: Audio::MinBars/Audio::MaxBars moved to src/core/constants.h with static_assert for even values, eliminating magic number duplication across CavaService, KCM, and QML.
Nix: Re-enabled Nix CI, release builds, flake.lock updater, and plasmazones.nix release asset now that nixpkgs-unstable has the Plasma 6.6 stack (NixOS/nixpkgs#479797).
