DFFs with REGMODE set to LATCH. All 12 variants are supported:

ast: Add support for array-to-array assignment
...
This commit adds support for SystemVerilog array-to-array assignment
operations that were previously unsupported:
1. Direct array assignment: `b = a;`
2. Array ternary expressions: `out = sel ? a : b;`
Both single-dimensional and multi-dimensional unpacked arrays are
supported. The implementation expands these array operations during
AST simplification into element-wise assignments.
Example of now-supported syntax:
```systemverilog
wire [7:0] state_regs[8];
wire [7:0] r[8];
wire [7:0] sel[8];
assign sel = condition ? state_regs : r;
```

abc9: preserve topological-loop asserts with targeted SCC fallback
...
A real-world ABC9 flow hit residual combinational loops after SCC breaking, tripping the prep_xaiger loop assertion.
Keep the existing topological assertions in place (prep_xaiger and reintegrate still assert no_loops).
To handle residual non-box loops, add a targeted fallback in prep_xaiger: when loops remain after normal SCC breaking, insert additional $__ABC9_SCC_BREAKER cuts on non-box loop cells, rebuild toposort, and then re-check the existing assertion.
Also keep pre-ABC9 SCC tagging on all cell types (scc -all_cell_types) and add a regression test (tests/techmap/abc9-nonbox-loop-with-box.ys).
