v0.2.0

Changed

• Dirty-tree handling is now pluggable. The clean-exit-dirty policy moved out of core into a dirty_handler hook; stash / ignore / auto_commit now ship as the bundled, default-on default_dirty_handler plugin. No behavior or config change for existing users — [vcs] dirty_action works exactly as before.

Added

• dirty_handler plugin seam (4th lifecycle hook) + DirtyOutcome on RoundResult; stash_orphan / try_auto_commit are now public api primitives. Consumers can fully own dirty-tree policy — see docs/migrations/0.2.0.md.
• dirty_auto_committed event (emitted when a handler auto-commits).
