Subject: [PATCH] fix(ci): retry template scaffolding on transient network
 failures

Each Test Templates leg scaffolds a fresh module and a fresh node_modules,
so every dependency is re-resolved from the Go checksum DB and the npm
registry. A single transient error there fails the whole matrix.

Retry the generate + build step up to three times, but only when the output
matches a known transient signature, so genuine template breakage still
fails on the first attempt.
