Remove orphaned native logging that nothing reached: - The /sdcard/Download zip dump (NativeCertGen.dump and the dumpLogs JNI, dump_logs_inner, dump.rs, pub mod dump), superseded by the diag.sh export. - The verbose-marker helpers (sysfs.rs, pub mod sysfs); the manual .verbose toggle still works via mod.rs::init's inline check. Drop the now-unused direct deps zip and libc and the orphaned jstring import. cargo ndk build is warning-clean.
