BLOCKING — Missing edit and delete prefix-collision scenarios (still)

Only read (line 185) and write (line 193) @tdd_issue_7478 scenarios are present. Scenarios for skill/file-edit and skill/file-delete with the sibling prefix collision path are still missing, despite the commit message and CHANGELOG both claiming coverage for all four tools.

Please add scenarios for edit and delete, plus corresponding step definitions step_when_skill_edit_sibling_escape and step_when_skill_delete_sibling_escape in features/steps/skill_file_ops_steps.py.
