v1.9.3 - Remove v0 Legacy Code (2025-12-29)

v1.9.3 - Remove v0 Legacy Code (2025-12-29)#

What Changed?#

This release removes v0 legacy code from the main v1 branch to reduce maintenance burden while keeping v0 available in a separate worktree for critical fixes. v0 source code (4,650 lines) and tests (540 lines) have been deleted from the v1 branch. The default CLI now exclusively uses v1, and all CI/CD pipelines have been updated accordingly.

  • v0 source code (src/haniwers/v0/) - 4,650 lines

🔧 Changed#

  • Default CLI (haniwers) now exclusively uses v1

  • CI/CD pipelines updated to run v1 tests only
