.SYNOPSIS
  Restore local-only WIP (stashes + untracked diffs) that was rescued into the
  recovery bundle's at-risk-work\ folder. Run AFTER the repos + submodules are cloned.

.DESCRIPTION
  guru-rmm  : each stashN-*.patch is applied to the working tree and then re-stashed,
              faithfully recreating the original `git stash` entries. Patches are
              processed highest-N-first so stash0 ends up on top (stash@{0}), matching
              the original LIFO order. The working tree is left CLEAN (changes live in
              the stash, exactly as before).
  guru-connect : tmp-spec018.diff was an UNTRACKED working file, so it is copied back
              into the repo as-is (not applied). Apply it yourself if/when you want it.

  Non-destructive and re-runnable. If a patch won't apply cleanly (submodule moved on),
  it is reported and the .patch file is left in place for manual `git apply --3way`.

.PARAMETER BundlePath        Recovery bundle root (auto-detect F:\ then E:\).
.PARAMETER ClaudeToolsRoot   Default D:\claudetools.
