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)

feat: exit node on NDI source format change

On status_change, probe() the new format and compare against the
format used to create the MXL flow. If resolution or fps changed,
throw with a descriptive message so the caller exits cleanly.

The existing catch in NDIInNode::run() logs the reason and breaks
out of the loop, causing the process to exit. Studio-manager detects
the exit and logs it — operator can restart to pick up the new format.

Same-format status changes (e.g. metadata only) still return false
and repeat the last frame as before.

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
