chore: remove POC route and skeleton wiring

Reverts skeleton template to match main — the POC route, workspace dep,
and generated type augmentation were local verification aids, not
part of the shippable package. Reviewers can restore them by checking
out the previous commit (see PR description for test instructions).

Why: keeping skeleton untouched in the merged PR avoids coupling this
hydrogen-api scaffold to a skeleton release and keeps the diff focused
on the new package itself.
