feat(engine): add hasPlanSkippedSteps and document plan DAG helpers

[kiannidev]

Closes #2298

Summary

• Add hasPlanSkippedSteps in @jsonbored/gittensory-engine — returns whether any step in a plan DAG was skipped.
• Document the plan DAG status helper surface in packages/gittensory-engine/README.md (advances the engine README export-list deliverable in docs(miner-foundation): gittensory-miner and gittensory-engine README + package docs #2298).
• Vitest coverage at 100% patch on the new helper.

Test plan

• COVERAGE_NO_THRESHOLDS=1 npx vitest run test/unit/plan-skipped.test.ts --coverage
• npx diff-cover coverage/lcov.info --compare-branch=main --fail-under=99 → 100%
• npm run build --workspace @jsonbored/gittensory-engine && npm run build:miner

⏸️ Suggested Action - Manual Review

Review summary
This adds a narrow pure predicate over the existing PlanDag shape, exports it through the engine barrel, documents it alongside the existing status helpers, and covers the empty, false, true, and barrel-export cases. The implementation matches the neighboring helper pattern and the linked issue scope is clear, so I do not see a blocking correctness problem in the visible diff.

Nits — 4 non-blocking

• nit: test/unit/plan-skipped.test.ts imports the helper directly from src for most assertions and only checks the barrel in a separate dynamic import; if package-consumer behavior is the contract, keeping the primary import through packages/gittensory-engine/src/index would exercise the public surface more directly.
• nit: packages/gittensory-engine/README.md lists the helper names but does not show the import path or a short usage example, which makes the new documented surface slightly less actionable for consumers.
• In test/unit/plan-skipped.test.ts, consider importing hasPlanSkippedSteps from ../../packages/gittensory-engine/src/index in the main test path and keeping only one assertion for the barrel behavior.
• In packages/gittensory-engine/README.md, add a compact example showing countPlanStepsByStatus and hasPlanSkippedSteps imported from @​jsonbored/gittensory-engine if the README section is intended as consumer-facing API documentation.

• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
