JohannesItten cc1011cced feat: NDI in node receives and writes audio flow 
- FlowDef.hpp: add make_audio_flow_def (NMOS IS-04 audio/Lnn flow)
- NDIReceiver: replace capture_v210 with capture() — single recv call
  dispatches to FrameKind::{Video,Audio,None}; AudioInfo struct carries
  sample_rate/channels/samples/channel_stride
- ndiin: optional audio writer when graph wires audio_flow_id; single
  loop with 5ms NDI poll; audio grains written immediately on arrival;
  video grains written when mxlGetCurrentIndex reaches video_index
- build_graph: rename ndiin video port flow_id → video_flow_id; add
  audio_flow_id edge (no sink yet — wired to ndiin only)

JohannesItten e6d72ab431 fix: ndiout — RAII for NDI lifecycle, vectors instead of malloc 
- NDIContext struct handles NDIlib_initialize/send_create/send_destroy/destroy
  so NDIlib_destroy() is guaranteed even if send_create fails (was leaked before)
- malloc/free for 10-bit and 16-bit frame buffers → std::vector<uint8_t>
- NDI frame structs point into vector data, no manual lifetime management
- static_cast for FourCC instead of C-style cast
- Tidy: ndi_frame_count replaces ndi_frame_counter, ++prefix form

JohannesItten 12c87db4e2 refactor: NDIHelper → NDIReceiver with cleaner API and naming 
NDIReceiver (shared/NDIReceiver.hpp):
- Rename class NDIHelper → NDIReceiver, file NDIHelper.hpp → NDIReceiver.hpp
- Add SourceInfo struct (width, height, fps_num, fps_den, stride, fourcc)
  replacing raw public member variables (xres, yres, frame_N, frame_D, stride)
- find_sources() now returns std::vector<std::string> instead of output pointer
- select_source() + get_source_info() → connect() + probe() (cleaner sequence,
  probe() returns SourceInfo and stores it internally for capture_v210)
- getV210_video_frame() → capture_v210() — removes unused source_num parameter
- get_bytes_per_pixel, fourCCtoStr → private static bytes_per_pixel, fourcc_str
- u_int32_t → uint32_t; (uint32_t) casts → static_cast
- probe() checks g_running to avoid hanging if source never sends video

ndiin/main.cpp:
- Update to new NDIReceiver API
- malloc/free latest_buffer → std::vector<uint8_t> latest_frame
- Remove unused #include <Processing.NDI.Lib.h> and V210.hpp
- memcpy uses latest_frame.size() instead of separate frame_bytes variable

JohannesItten 7a32fa20af fix: NDI node correctness and robustness fixes 
NDIHelper:
- find_sources: check g_running each attempt to avoid 50s block on shutdown
- getV210_video_frame: fix P216 branch (fall-through + local pointer reassignment bug)
- getV210_video_frame: status_change re-queries source info instead of throwing
- select_source: fix typo "recieve" → "receive"

ndiout:
- set frame_rate_N/frame_rate_D on the NDI send frame (was 0/0)
- add per-second stats logging (matching fakesink pattern)
- add missing <chrono> include
- fix typo "reciever" → "receiver"

ndiin:
- read source_num from NODE_CONFIG (key: "source_num", default 0)
- wrap hot-loop NDI call in try/catch so source-lost terminates cleanly
- pass source_num through to getV210_video_frame

JohannesItten ca682eaf0a Initial commit: testpattern → fakesink pipeline over MXL shared memory 
- NodeBase, Signal, FlowDef, V210 shared headers
- testpattern node: SMPTE 75% color bars writer at 25fps
- fakesink node: non-blocking MXL reader with per-second stats
- studio-manager: FlowGraph data model, graph-driven fork/exec launcher
- mxl pinned as submodule at 0ae1dc5
