core: merge oak-common into oak-core
oak-common is gone; its modules (configstore, xmlutils, ocioutils,
oiioutils, colormath, colortransform, videoparams, ffmpegutils, ...)
now live in oak-core alongside the value types. The render value/GPU
types moved too: backend (wgpu context + DisplayRenderer), color
(ColorProcessor over ocio-rs), texture, frame, and the commonutil
config helpers.

Fix-ups to make the merged tree build and pass tests:

- oak-core Cargo.toml: wgpu back to 25 (the moved backend code is
  written against that API generation); add the toml/quick-xml/image
  deps oak-common carried.
- lib.rs: drop the duplicate 'pub mod error;'.
- error.rs: unified OAKCORE_* codes; restore Error::new() and
  From<OcioError> from oak-common's error type.
- backend.rs/color.rs: oak_core::/oak_render:: self-references
  rewritten to crate::; the shaderfx-dependent GPU effect test moved
  to oak-render's shaderfx tests (shaderfx depends on oak-node and
  cannot live in oak-core).
- oak-render's error module re-exports oak_core::error::{Error,
  Result}; the OAKRENDER_* codes stay as the public-code contract.
- oak-node jobs.rs: ColorProcessor imported from oak_core::color.
- Integration tests repointed at oak_core::{texture, frame, backend,
  color, colormath}.
- the display-ICC regression test treats an empty OAK_DISPLAY_ICC as
  unset, matching displayicc::env_override_icc.

oakaudio 类覆盖映射表(C++ audio 模块 → oakaudio Rust crate)

逐类盘点 src/audio/src 与 src/audio/c_api。每一行标注 Rust 侧落点。 // CPP-PARITY 注释义务不变:凡承载布局/数值/边角行为的地方,标出 C++ 文件:行号。本表是初稿;实现阶段据实核对。

1. AudioManager(manager.rs)

C++ Rust 落点
AudioManager::create_instance / destroy_instance / instance manager::create_instance / destroy_instance / instance(OnceLock<Mutex<ManagerInner>> 单例)
set_output_notify_interval / set_output_notify_callback manager::set_output_notify_interval(notify 回调经 guard 从 PortAudio 线程调用,见 previewdevice.rs)
push_to_output / clear_buffered_output / stop_output manager::push_to_output / clear_buffered_output / stop_output
seconds / reset_output_clock manager::seconds / reset_output_clock(播放时钟补偿输出延迟)
get/set_output_device / get/set_input_device manager 设备访问器(PaDeviceIndex,-1 = paNoDevice)
hard_reset manager::hard_reset(关流并重初始化 PortAudio)
start_recording / stop_recording manager 录音(经 bridge::codec OakEncoder,恒定 interleaved f32)
find_config_device_by_name / find_device_by_name(static) manager::find_config_device_by_name_s / find_device_by_name_s
get_port_audio_params / get_port_audio_sample_format(私有) manager 内部(映射 AudioParams ↔ PortAudio;// CPP-PARITY 标注格式映射)

2. AudioProcessor(processor.rs)

C++ Rust 落点
open(from,to,tempo) / close / is_open processor::open / close / is_open(FBAudioGraphConfig 组装)
convert processor::convert(planar f32 进/出;fb_audio_graph_push + fb_audio_graph_pull)
flush processor::flush(fb_audio_graph_push channel_data==NULL)
from() / to() processor 保存的 AudioParams

3. AudioSynchronizer(synchronizer.rs,纯静态)

C++ Rust 落点
place_by_source_time synchronizer::place_by_source_time
place_by_waveform_offset synchronizer::place_by_waveform_offset

4. AudioLevelMeter(levelmeter.rs,纯静态)

C++ Rust 落点
analyze_sample_buffer levelmeter::analyze(peak/RMS/VU 阈值与 -200 地板;// CPP-PARITY 标注)
linear_to_db / power_to_lufs(私有) levelmeter 内部(BS.1770 LUFS,无 K-weighting)

5. AudioVisualWaveform(waveform.rs)

C++ Rust 落点
构造 / channel_count / set_channel_count / length waveform::Waveform + 访问器
overwrite_samples waveform::overwrite_samples(mipmap 展开,k_minimum/maximum_sample_rate)
overwrite_sums / overwrite_silence waveform::overwrite_sums / overwrite_silence
trim_in / mid / resize / trim_range waveform::trim_in / mid / resize / trim_range
get_summary_from_time waveform::get_summary
sum_samples / re_sum_samples(static) waveform::sum_samples / re_sum_samples
mipmap 内部(overwrite_samples_from_* / get_mipmap_for_scale / time_to_samples / validate_virtual_start) waveform 内部
全文件提取(c_api oakaudio_waveform_extract) waveform::extract(经 bridge::codec decoder + bridge::ffmpeg)
SamplePerChannel POD 与 oakaudio_min_max static_assert 对齐(// CPP-PARITY: c_api/waveform.cpp)

6. AudioWaveformSync(waveformsync.rs,纯静态)

C++ Rust 落点
extract_rms_envelope waveformsync::extract_rms_envelope
estimate_offset(SampleBuffer 版) waveformsync::estimate_offset(内部先提取 envelope)
estimate_envelope_offset(两个重载) waveformsync::estimate_envelope_offset(valid 掩码版为权威)
estimate_stretch_and_offset waveformsync::estimate_stretch_and_offset(O(rateslagsoverlap))

7. PreviewAudioDevice(previewdevice.rs,header-only)

C++ Rust 落点
read / write previewdevice::PreviewAudioDevice::read / write(回调侧 pull)
set_params / bytes_per_frame / set_bytes_per_frame previewdevice(AudioParams → bytes_per_frame)
set_notify_interval / set_notify_callback previewdevice(notify 回调,锁外触发)
clear previewdevice::clear
add_output_frames / output_frames_consumed / reset_output_frames previewdevice(atomic 播放时钟)

8. audio_config 命名空间(config.rs,不是类)

C++ Rust 落点
output_buffer_size() config::output_buffer_size(oak_core_config_get_int(nullptr,"AudioOutputBufferSize",0))
device_name(is_output_device) config::device_name(oak_core_config_get 两阶段;key = "AudioOutput"/"AudioInput")

9. 刻意不迁移(drop)

C++ 理由
get_port_audio_params 的 PortAudio 平台细节 归 bridge::ffmpeg/PortAudio 侧;Rust 保留语义与默认布局兜底
Qt 常量(qFuzzyIsNull 等)内联展开 语义内联为 Rust 比较;// CPP-PARITY 标注
draw_sample/draw_waveform(QPainter) UI 绘制归 facade/app;crate 只存/汇总数据
