  fix: add mutex protection to etagResponseWriter (#71)

The etagResponseWriter had a potential data race on the buffer field
  and state fields (hasWritten, written, skipETag, finalized) when
  Write() and Flush() were called concurrently.

  Changes:
  - Add sync.Mutex to etagResponseWriter struct
  - Create writeHeaderLocked(), writeLocked(), finalizeLocked() internal methods
  - Update public methods (WriteHeader, Write, Flush, finalize) to use locking
  - Add TestETag_ConcurrentWriteAndFlush to verify thread safety
