v0.0.16

Added

• Feature-gated pipeline operator token (pipeline_op):
  • Optional lexer support for tokenizing |> as a single PipeGreater token behind the pipeline_op Cargo feature.
  • Chunked lexer cross-chunk merge handling for | at end-of-chunk followed by > at start-of-next-chunk when pipeline_op is enabled.
  • Tests for both feature-off (default) and feature-on behavior.

Changed

• Documentation:
  • Updated LANG_SPEC.md to clarify that |> remains reserved at the language level for post-v0.1 semantics, while lexer tokenization can be feature-enabled.
  • Updated compiler/medic_lexer/README.md to document pipeline_op and corrected test commands.
• Release alignment:
  • Bumped workspace crate versions to v0.0.16.
