Merge branch 'master' into v4

Resolve 57 conflicts keeping v4's architecture (UI removal, api app
context, path isolation, streaming/codecs/rtc, workflow-mode superset,
args_helper) and taking master's post-fork features so none are dropped:
inference override/adjust provider hooks (+ face_swapper 3.8.1 coreml
fix), is_vision_frame validity guards, resolve_temp_frame_set frame
numbering with the source audio/voice trim offset, the ffmpeg color
pipeline (restrict_color_transfer / convert_color_space / temp_pixel_format),
ffprobe select_stream v:0 + format duration, pre_check ffprobe with
dependency_not_installed, onnxruntime arena-leak guard + version lru_cache,
installer cuda@12/@13 provider split, workflow_strategy disk/memory
(memory default), and the dependency version bumps. content_analyser hash
guard rehashed to 3c6ce25e.
