Patchwork Harness v0.4.0

Added

• continue [instruction] (also run --continue, MCP harness_continue): picks up the last run in this directory, or --session <id>, where it stopped.
  • Resume. A run that stopped part-way re-runs its own plan from the first unfinished step, with no new planning. That covers a failed or refused step, the spend ceiling, a killed process, or a dry run.
  • Follow up. A run whose steps all ran gets one direct step on what was left: a step out of tool turns, a failing test gate, or an INCOMPLETE review. An instruction rides along, or is the follow-up itself on a run that finished clean.
  • The earlier run's gate and review apply again.
  • Tested live: a real run was killed after step 1, then continued twice to completion, for about $0.006.

Fixed

• A step that used all its tool turns was recorded as completed, with no warning. It is now flagged (turn_cap) and warned about, and a resume gives it more turns.
• The session file was written only when a run ended, so a killed run left nothing to pick up. It is now saved after the plan and after every step, atomically.
