is-in-ci feeds the `interactive` default (render.ts:503) and shouldSynchronize
(write-synchronized.ts:9). vue pinned ^1.0.0 vs Ink's ^2.0.0, whose CI-detection
formula differs: v1 scans for any `CI_*`-prefixed var and gates the whole expression
on CI not being falsy; v2 independently checks `CI` and `CONTINUOUS_INTEGRATION` and
drops the prefix scan. The common cases (local CI=false, GitHub CI=true) are identical
on both, so the suite and CI are unaffected; only edge env configs diverge. Bumping to
^2.0.0 makes vue's CI detection byte-identical to Ink's. Locked by a test
(CI=false + CONTINUOUS_INTEGRATION=true → true, which v1 would report false).
