v2.12.1

Fixed

• Escape literal | characters inside table cells while leaving pipes inside <code> and <pre> untouched to avoid rendering backslashes in code spans/blocks (fixes #140).
• Handle nested tables without double-escaping pipes and add regression coverage for table cells containing code spans/blocks and nested tables.
• Preserve link-only list items when word wrapping is enabled so nested link lists are not merged or reflowed (fixes #143); added regression fixtures for the reported table-of-contents sample.

Changed

• Updated dependency locks/manifests to align with the 2.12.1 release.
• Downgraded Java Maven compiler/source plugins back to 3.x to keep CI builds compatible with Maven 3 runners.
