v0.17.8 — ghost-turn recovery and persistent goal chips

What changed

• Recovers OpenCode UltraGoal roots from ghost-turn and duplicate turn.submit failures before compact/continue.
• Prevents wedge recovery and progress check-ins from racing a second start.
• Revives transiently blocked roots and treats already-active / missing ACP session failures as recoverable.
• Keeps the left-sidebar UltraGoal chip for every durable goal state—running, paused, blocked, limited, or complete—until the goal is cleared, matching the right pane.
• Replaces the failure-prone sidebar crew payload with a lightweight validated projection and adds regression coverage.
