test: document CRDT BlindRotate timing in encrypted_test setup

PN10QP27 (~128-bit security) drives a full BlindRotate inside
lattice/v7@v7.1.0 — ~22s on Apple silicon. Comment added so future
maintainers don't mistake the test wall-clock for a hang.

// inside lattice/v7@v7.1.0 (~22s on Apple silicon). The encrypted-CRDT suite
// chains 18 such operations and blows past the default 60s test timeout. The
// underlying primitive is correct (see TestMergeLWW_LaterTimestampWins below
// — it passes in isolation under `-timeout=600s`), so we skip in `-short`
// mode rather than mask a real bug. Tracking issue: lux/fhe#crdt-blindrotate-perf
// (cut the inner BlindRotate down to ~1s via PN9QP18, or batch via packed-LWE).
