Agents weren't auto-executing after gt handoff because the SessionStart
hook only outputs text - it doesn't inject a prompt. Claude needs actual
user input to trigger a response.
The fix: pass "gt prime" as an argument to claude, just like gt crew at
already does. This treats the argument as the first user prompt, which
triggers GUPP execution immediately.
