 * Tests for /gsd-edit-phase (#2617)
 *
 * Covers:
 *  - Command file and workflow file existence
 *  - Single-field edit instructions
 *  - Full-phase regeneration from clarified intent
 *  - Invalid depends_on blocks with clear error
 *  - Guarded edit of in_progress phase without --force
 *  - --force override of status guard
 *  - Invalid phase number produces clear error
 *  - Diff + confirmation before writing
 *  - Phase number and position are preserved
