Make logging init idempotent (swallow SetGlobalDefaultError on repeat
call), remove unused dumpLogs JNI params that violated the API contract,
and strip dead public_key_spki field + build_ec_spki() that were
computed on every keygen but never consumed by the cert builder.
Multi-output logging via tracing: /dev/kmsg for logcat, rotating file
appender (512KB, 3 files), stderr for debug. Diagnostic ZIP dump with
log files and TEE status snapshots. Verbose toggle via JNI flag or
.verbose marker file.
