HOK-1391: Add explicit plan critique to eval judge

[timogilvie]

Summary

• Adds a planCritique rubric to the eval judge that scores plans directly across five dimensions: component_boundaries, invariant_coverage, approach_soundness, missed_patches, and overall
• Introduces a standalone tools/prompts/plan-critique.md prompt for evaluating plans in isolation (useful when you have the plan and diff but want a focused critique without running the full eval)
• Bumps the eval schema to v1.9.0 with PlanCritique / PlanCritiqueDimension TypeScript interfaces and attaches the critique to the plan stage score when available
• Enables direct model comparison on planning quality without inferring it purely from downstream diff cleanliness

Changes

• tools/prompts/eval-judge.md — new Plan Critique section instructs the judge to emit planCritique when an implementation plan artifact is present
• tools/prompts/plan-critique.md — new standalone prompt for targeted plan evaluation
• shared/lib/eval-schema.ts — v1.9.0: PlanCritique, PlanCritiqueDimension types; planCritique field on StageScore
• shared/lib/eval-record-builder.ts — attachStageOutcomes now accepts and attaches planCritique to the plan stage
• shared/lib/eval-schema.test.ts, eval-record-builder.test.ts, eval.test.js, llm-cli.ts/test.ts — schema version bump and related test updates
• tests/lifecycle-harness.test.sh, tests/lifecycle-scenarios.test.sh — stub _restore_inflight_task_window_if_missing to fix lifecycle harness tests

Test plan

• Existing eval schema tests pass with the v1.9.0 schema version
• eval-record-builder tests confirm planCritique is attached to the plan stage when provided and omitted otherwise
• Manually verify that the eval judge prompt produces a planCritique object for workflows that include an implementation plan and omits it when the plan is unavailable
• Standalone plan-critique.md prompt can be used directly with a task prompt + plan content + optional diff

Self-review

• Review tool verdict: ready (exit code 0, no findings)
• Iterations run: 1
