Self-consistent .inputs metadata across all variants

build.py: cmd_inputs always pads or trims the inferred input list to
match the gate's weight fan-in. Pattern matchers in
infer_inputs_for_gate cover most circuit families, but a few seed-file
families (arithmetic.expr_paren.mul, arithmetic.multiplier8x8,
alu.alu32bit.div, etc.) still produce wrong-length lists; those now
get anonymous gate-local placeholders so .inputs is always
self-consistent with .weight.

build.py: cmd_inputs drops every pre-existing single-gate .inputs
tensor before regenerating, since signal IDs are session-local and
any prior IDs reference stale registry entries. Packed multi-gate
tensors (weight.dim() > 1) are left untouched.

build_all.py: re-runs `build.py inputs` after each per-variant quantize
step, so routing metadata reflects the gates that --ternary adds
(modular detectors gain ~3000 new gates per variant).

After this pass and a fresh quantize --ternary across variants/ + the
canonical, the safetensors2verilog converter reports zero stale
.inputs gates on neural_alu8.safetensors. All 18 variants still pass
eval_all.py at 100% fitness.
