- Fix Bug #999 order: merge → verify → remove worktree → delete branch
(avoids losing work if merge fails after worktree removal)
- Add submodule guard to Step 0 detection (GIT_DIR != GIT_COMMON is also
true in submodules)
- Preserve global path (~/.config/superpowers/worktrees/) in detection for
backward compatibility, just stop offering it to new users
- Add step numbering note and implementation notes section
- Expand provenance heuristic to cover global path and manual creation

Design for detect-and-defer worktree support. Superpowers defers to
native harness worktree systems when available, falls back to manual
git worktree creation when not. Covers Phases 0-2: detection, consent,
native tool preference, finishing state detection, and three bug fixes
(#940, #999, #238).
