  -----------
  [analyzer] Refine default binding preservation in RegionStore (#189319)

Narrow the new setImplicitDefaultValue() guard so existing default
bindings are preserved only for aggregate-like cases.

The previous change was too broad and regressed normal
zero-initialization, causing new int[10]{} to be modeled as undefined
and emit a garbage-value warning instead of the expected analyzer
reports.
