cristhian c1a7d70ba6 add typed Arrow payloads and a dora-image-view dataflow
dora-image-view takes std/media/v1/Image, and dora's compatibility graph
has no edge from std/core/v1/UInt8 to it, so wiring the two failed
`dora validate` whatever the node actually sent. Its flat-buffer fallback
would not have decoded these frames either: it reads width/height
metadata, and this node only published shape.

image and depth now go out as the Image struct, camera_info and
point_cloud as Float32 arrays and camera_state as a string, all built
against the Arrow C data interface in src/arrow so the node still links
no Arrow C++. Shape, dtype and encoding metadata are dropped where the
payload describes itself; intrinsics, frame_id and both timestamps are
unchanged. tests/run.sh covers the packing without a camera or the SDK,
round-tripping each array through pyarrow and rebuilding it under the
sanitizers.

Breaking: image_bgr is renamed to image and every payload changes shape.
dataflow_plot.yml is replaced by dataflow_view.yml, which wires the
viewer from a tag and repeats its contract in input_types so validate
checks both sides of the wiring.

# Two gates, neither of which needs a camera, the ZED SDK or CUDA: the dataflows
# are checked against the typed contract in dora-node.yml without running the
# node, and the payload packing is compiled and tested on its own.

# strict_types: true in each dataflow turns a type warning into a
# non-zero exit, so a mismatched annotation fails here rather than at
# runtime. The viewer file is checked too: it wires the same outputs, and
# a rename that breaks only the consumer should still fail the build.
