fix: module-level arrays with Unknown/Any type crash on Android (v0.4.28)

- analyze_module_var_types set is_union=true for Unknown/Any HIR types
- functions.rs loaded module vars as F64 when is_pointer && is_union
- Init stored I64 (raw pointer) but functions loaded F64 — type mismatch
  corrupted array pointers on Android (FP flush-to-zero)
- Arrays/closures/maps/sets/buffers now always use I64 regardless of is_union
- Also reverted the perry-ui-android JNI_GetCreatedJavaVMs stub (now handled
  by C stub in linker step from v0.4.27)

 ## Recent Changes
 
+### v0.4.28
+- fix: module-level arrays/objects with `Unknown`/`Any` HIR type loaded as F64 instead of I64 in functions — `analyze_module_var_types` set `is_union=true` for Unknown/Any, causing `is_pointer && !is_union` to select F64; init stored I64 but functions loaded F64, corrupting pointers on Android (FP flush-to-zero); now arrays/closures/maps/sets/buffers always use I64
+
 ### v0.4.27
 - fix: Android `JNI_GetCreatedJavaVMs` undefined symbol — `jni-sys` declares extern ref but Android has no `libjvm.so` (`libnativehelper` only at API 31+); Perry's linker step now compiles a C stub `.o` and links it into the `.so`
