* feat(native): decode Android .note.android.ident ELF notes Decode Android NDK NT_ANDROID_TYPE_IDENT (.note.android.ident, owner Android, type 1) notes in inspect_elf_notes across legacy 4-byte and modern >=132-byte descriptors with bounded TextBudget accounting. * fix(native): isolate Android note scan budget test, scope contract import, and add feature spec * test(native): use domain tool contract in elfNotesMcp boundary test
