Garry Tan 7396f04847 test(plan-tune): de-flake "derive pushes scope_appetite up"
The test was ~25-50% flaky (worse on main). gstack-question-log fires a
fire-and-forget background `--derive` after every write; the 5 rapid log writes
spawned 5 racing background derives that collided with the test's explicit
--derive — a late one that only saw 3 entries could clobber
developer-profile.json after the explicit one wrote sample_size=5.

Set GSTACK_QUESTION_LOG_NO_DERIVE=1 (the flag the binary documents for exactly
this case) so the writes don't spawn background derives. The explicit --derive
still runs, so real derive behavior is still asserted. 20/20 green after.
