## Breaking changes
  This release renames every public function from camelCase / PascalCase to snake_case. All v2.x callers will need to update.

  | `minkReduce`          | `mink_reduce`           |

  | `isMinkReduced`       | `is_mink_reduced`       |                                                                                                                     
  | `orthogonalityDefect` | `orthogonality_defect`  |

  `RandLowerTri` is also un-exported in this release; access it as `MinkowskiReduction.rand_lower_tri` if needed.                                                         
                                                                                                                                                                          
  ## Other changes                                                                                                                                                        
  - Library functions no longer `println` to stdout: `is_mink_reduced` now logs `@debug` messages when conditions fail. Set `ENV["JULIA_DEBUG"] = MinkowskiReduction` to
  see them.                                                                                                                                                               
  - Argument errors now throw specific exception types (`ArgumentError`, `DomainError`, `DimensionMismatch`, `OverflowError`) rather than generic `ErrorException`.
  - Matrix-form wrappers (`mink_reduce(M)`, `is_mink_reduced(M)`, `orthogonality_defect(M)`) now validate that `M` is exactly 3×3 and throw `DimensionMismatch` otherwise.
  - Internal cleanup: `@views` on the matrix wrappers, `Int64` → `Int`, dropped `using Random` from the source.
