Commit Message

perf: cache per-node facts in DesignScanner to eliminate redundant walks (#63)

Compute predicates ('has addressable children', 'has only external
addressable children'), nested array strides, and rel_path once during
the existing DesignScanner walk and store them on DesignState keyed by
node path. Downstream listeners (BusDecoderListener, StructGenerator,
DecodeLogicGenerator, FanoutGenerator, FaninGenerator) read from the
cache instead of re-iterating node.children() and recomputing strides
on every pass. Also memoize get_addressable_children_at_depth.

The scanner now continues into external-addressable subtrees so meta
is populated for nodes the listeners still visit; property collection
is still skipped for external nodes to preserve prior behavior.
