Bug Fixes

• String NaN-boxing in function calls — is_string locals (I64 raw pointers) passed to functions expecting F64 now use js_nanbox_string (STRING_TAG 0x7FFF) instead of inline_nanbox_pointer (POINTER_TAG 0x7FFD). Fixes textfieldGetString return values becoming undefined when used in encodeURIComponent, ||, or cross-module calls (GH-10, GH-11, GH-12)
• JS interop string args — js_call_function and js_native_call_method fallback paths now properly NaN-box string arguments with STRING_TAG instead of raw I64→F64 bitcast

Performance

• Direct object field access — PropertyGet/PropertySet on variables assigned from object literals now use direct offset loads/stores (24 + idx*8) instead of js_object_get_field_by_name runtime lookup, when field ordering is known at compile time
• Object field cache upgraded — 3-tuple entries (keys_ptr, key_hash, field_index) for collision safety, 1024 entries (up from 512)
