New hardware/v3/rtl/n2_system_top.v: synthesis wrapper around the
EXP-0066-verified system (neural_director_packed.v + arbiter + real
SDRAM controller + 2 real packed_slot.v instances).
Real Vivado post-route: 16/240 DSP48E1, WNS -2.570ns @ 200MHz ->
Fmax ~132.1MHz -- only -2.1% vs the isolated single core (134.9MHz,
EXP-0059). Unlike V2/ECP5 (where the real full-system Fmax was
measurably lower than the isolated-core number), this Director+
arbiter architecture shows no comparable penalty at N=2, real
confirmation (not projection) that the earlier ~55-85x-over-ESP32-S3
estimate's key assumption holds at this scale.
Full writeup in hardware/v2/logs/experiments.log EXP-0067.
