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.

# The camera into dora-image-view, and the worked example of wiring this node to
# a consumer.
#
# dora has no cross-dataflow wiring, so the camera node is declared here too
# rather than referenced — run this file or dataflow.yml, not both.
#
# Run it with `--uv`, which gives the viewer its own managed environment:
#
# dora run dataflow_view.yml --uv
#
# Fetching the viewer needs anonymous read access to its repository. dora-cli
# 1.0.1 fetches through libgit2 with no credential callback, so ssh:// cannot
# authenticate at all; on Gitea, marking the repository public is not enough
# either, since a repository inside a private organization answers an anonymous
# clone with 401.
