v0.6.0

Fixed

• Rollback no longer wipes non-automator files. A failed in-place attempt previously ran
  git reset --hard + a blanket git clean -fd over the whole checkout, which could delete a
  project's _bmad-output/ and any other untracked files (only .automator/ and two artifact
  subdirs were spared). The orchestrator now never runs a blanket git clean: it reverts the
  attempt's tracked changes and removes only the untracked files that run created, preserving
  pre-existing untracked files and the entire _bmad-output/ tree.

Changed

• Auto-rollback is now opt-in ([scm] rollback_on_failure, default off). With it off the
  orchestrator never touches your working tree on a failed attempt — it pauses the run with bold
  manual-recovery instructions (back up untracked files → git reset --hard <baseline> → restore).
  Turn it on for the safe automatic rollback above (it discards the attempt's uncommitted work, so
  it warns when it fires). Worktree isolation (scm.isolation = "worktree") sidesteps this entirely.
