Milestone 'Strategy node vocabulary I — temporal, logic, resample & session':
the 7 aura-std nodes (EqConst, Gt, And, Delay, Latch, Resample, Session) plus a
synthetic e2e fixture, driven by the GER40 15m session-breakout. Records the
design pass's cross-cutting decisions: close-instant timestamp convention,
Latch emits f64 (Exposure dropped from the DAG), the EqConst i64->bool gate,
the Resample-only Barrier(0) firing regime, and the build order. refs #84-#91.
