Replace ReInterHand shared-v1.0 with the verified shared-v1.1 release (candidate PR) (#8)

"""CONTRACT 6.5: read complete sequences through the v1.1 reader, every component.
Acceptance item 5 asks for a check the byte-level ones cannot give. ``verify.py``
compares a view's bytes against its own v1.0 source, which proves repackaging preserved
them, but it never decodes media and never crosses views -- a release whose bundles are
each individually byte-perfect and whose RGB, camera and annotations no longer line up
would pass it. ``validate.py`` crosses components, but per view and against the schema,
on a tree whose media may not be materialised.
So this opens the finished release the way a consumer would, through ``BundleReader``
and the registry, and checks the joins:
frames the RGB's real packet count (ffprobe, demux only -- ``nb_frames`` is absent
in Matroska) equals the metainfo ``num_frames``, and so does every field's
``T`` axis, the length of ``frames.jsonl`` and both standalone validities
pixels where the media is materialised, its decoded width and height equal the
view's declared ``camera.image_size``, which the contract defines as
``[W, H]`` -- so the ffprobe ``width`` is compared with the first element
and ``height`` with the second, and the exo views' 667-wide by 1024-tall
portrait frames are a match rather than a transposed declaration. What the
file really is -- codec, pixel format -- is recorded. The declared ``rgb``
storage profile is one of the gaps ``DECLARED_MEDIA_SCHEMA_GAPS`` names, so
the media has to be measured rather than believed
camera the directory the view lives in, its ``camera_id``, its ``camera`` block
and the intrinsic component's ``schema_id`` all name the same camera
presence every declared file opens, or is absent exactly as the media declaration
says. A half-pulled sequence fails from either side
sequence the sequence-wide joins: one capture, one segment, one span, one split,
and a sequence id that is exactly ``<capture>__<policy>__<start>__<end>``
cameras ReInterHand's own join -- what RHD's shared visibility attribute is for it.
The cameras of a sequence have to agree about which source frames they
saw. Measured over all 500 sequences: the per-segment cells store the
same source frames in the same order from every camera, and the per-frame
cells' exo renders are a strict subset of the ego render. That is why
``sync_id`` works as a join across cameras here, and why the ARCTIC rule
("every camera the same frame count") must not be copied: ego renders at
30 fps and exo at 5, so their frame counts differ by design.
What it does not do: it never decodes pixels, compares an image to anything, or forms an
opinion about whether a mask looks right. CONTRACT 6.5 keeps that -- human visual
acceptance -- separate from this, and this tool is on the packaging side of that line.
