fix(coding-agent): widened tiny-title worker smoke timeout for slow runners

The release_binary smoke probe spawns the tiny-title worker as a cold subprocess
of the compiled binary and pings it. On the contended macos-15-intel runner the
cold start (decompress + module-graph load, with a cold bun cache) blew past the
5s bound and failed the 15.10.3 release, while arm64/linux/win passed. The probe
only needs to prove the worker spawns and ponges at all, so the timeout is raised
to 30s — a dead worker still never ponges, so the check is unchanged in substance.
