This PR adds a comprehensive test suite for ZStreamAspect

Changes -

• Tests for annotated aspect:
  • Verifies that single and multiple log annotations are actually added to the stream using ZIO.logAnnotations.
• Tests for rechunk aspect:
  • Verifies that the stream is properly rechunked to the specified size and that all elements are preserved.
• Tests for tagged aspect:
  • Verifies that metric tags are actually added to the stream using ZIO.metricTags.
• Tests for aspect composition:
  • Verifies that multiple aspects (e.g., annotated and rechunk, rechunk and tagged) work together and both their effects are applied.
