* refactor(platforms): sink the shared src/platforms root files into their substrate homes (#2082 W3)
The shared files left directly under src/platforms move onto a declared
owner: provisioning mechanics (install-source family, toolchain probing,
boot-failure classification, app-resolution caching) form
@agent-device/provision-kit above capture-kit; host mechanics resolve to
host-kit's seams; kernel takes the pure numeric helpers; contracts keeps
vocabulary only.
Settings parsing, command-attempt rendering, and the unsupported-interactor
factory stay with their families rather than pooling in a substrate
package: android and apple settings each own their parsing, and the
unsupported-interactor factory lives in root core with a vega-local copy.
A platforms-root-shape rule rejects any new shared file or directory
appearing directly under src/platforms, and the provision-kit direction
gates (no platform imports in, no capture-kit importer) are planted red.

* test: cover the family-owned parsers and the unsupported-interactor factories
The settings parsers and the unsupported-interactor factory arrived without
owning tests, so their branches rode on callers. Each now has one: the
appearance/state parsers over every accepted spelling and their rejections,
the attempt summarizer over its arg join and stderr budget, and both
interactor factories over the whole operation surface and the per-instance
label.
Also drops the duplicate ./snapshot-desktop-projection export key that a
rebase left in capture-kit's manifest, where JSON silently keeps the last,
and the root-shape docblock the violation message already states.
