Subject: [PATCH] fix(examples): derive assemble-examples list from the
 capability registry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The examples deploy (threadplane-examples) hardcoded which apps to stage,
and drifted from the registry — tool-views/json-render/a2ui were added to
the registry but never to this list, so they 404'd in production. Derive the
staged-example list from the capability registry (the documented single
source of truth, already used by the Railway deploy generator) so a new cap
can never be silently dropped from the frontend deploy again.

Verified: derives all 36 caps incl. the 3 new ag-ui examples; import resolves
and the script runs.
