- FileLogSink: thread-safe file writer with AutoFlush, FileShare.Read for
concurrent read access (tail -f), automatic parent directory creation,
full date-time timestamps, IDisposable for graceful shutdown
- CompositeLogSink: fan-out to multiple sinks with per-sink exception
isolation (one broken sink cannot silence the others), IDisposable
propagates to children
- SharpEmuLog: ResolveSinkFromEnvironment() reads SHARPEMU_LOG_FILE and
creates CompositeLogSink(console + file) when set; Sink setter now
disposes the previous IDisposable sink to prevent file handle leaks;
Shutdown() flushes and disposes the active sink
- Program.cs: Main wrapped in try/finally to guarantee SharpEmuLog.Shutdown()
runs on all exit paths (GUI, mitigated child, normal, exception)
