* perf(logging): flush file transport asynchronously off the request path
* fix(ci): record flushLogger surface growth and drain before log reads
- +1 public export/callable budget with annotation: logger file-transport
flush for graceful shutdown drains; regenerate SDK API baseline
- three tests that read the log file right after logging now drain the
async file transport first (flushLogger) instead of racing the flusher
* test: drain async log transport before reading talk and request-trace logs
* test: drain async log transport in CLI logger file tests
* test: drop unused withTempDirSync import
