Reviewer's GuideAdd a new ambient-brightness plugin that exposes org.deepin.dde.AmbientBrightness1 on D-Bus, implements continuous ambient light based brightness recommendation with hysteresis/debounce and lifecycle handling, wires it into the Qt plugin build, and refactors existing power and shortcut code to rely on the new DBus state instead of the old DConfig toggle, preventing conflicts with power save brightness adjustments.

1. Add an ambient brightness service backed by iio-sensor-proxy 2. Convert lux samples into stable brightness recommendations with filtering, hysteresis, and debounce 3. Coordinate sensor lifecycle with lid, sleep, session, service, and configuration state Influence: 1. Publish automatic brightness state and recommendations through org.deepin.dde.AmbientBrightness1 2. Prevent power-saving and manual brightness paths from conflicting with ambient brightness 3. Verify sensor lifecycle and brightness policy with unit tests fix: 支持环境光自动亮度调节 1. 新增基于iio-sensor-proxy的环境光亮度服务 2. 通过滤波、滞回和防抖将lux样本转换为稳定的亮度推荐值 3. 根据合盖、休眠、会话、传感器服务及配置状态管理光感生命周期 Influence: 1. 通过org.deepin.dde.AmbientBrightness1发布自动亮度状态及推荐值 2. 避免省电及手动亮度调节路径与环境光自动亮度冲突 3. 通过单元测试验证光感生命周期及亮度策略 PMS: BUG-372191

…ess plugin
Add a new ambient-brightness plugin that reads lux from iio-sensor-proxy, applies filtering, hysteresis, and debouncing, and publishes recommended brightness via DBus (org.deepin.dde.AmbientBrightness1). Refactor the power plugin to remove the old DConfig-based ambient brightness toggle, add isAmbientBrightnessActive() guard to PowerSavePlan so brightness save-plan operations don't conflict with ambient auto brightness. Remove redundant auto-brightness disable logic from dde-shortcut-tool since Display1.ChangeBrightness already calls prepareManualBrightnessChange() which disables ambient brightness via DBus.
新增环境光自动亮度插件，从 iio-sensor-proxy 读取 lux 值，经过滤波、滞回
和防抖处理后通过 DBus 发布推荐亮度。重构 power 插件，删除旧的 DConfig
自动亮度开关，在 PowerSavePlan 中添加 isAmbientBrightnessActive 守卫避免 省电计划与自动亮度冲突。移除 dde-shortcut-tool 中冗余的自动亮度关闭逻辑
（Display1.ChangeBrightness 已通过 prepareManualBrightnessChange 处理）。
