test(design): plan-mode names its read list and caps its additions and summary

At 6fcb0981 plan-design-review-plan-mode timed out at 300 s (9 turns): 22 cat/sed
chunk reads (~50 s), then a 28 KB plan Write (~150 s), before the read-back
finished. The 9a7a7e54 pass took 240 s with a 24.6 KB Write. Read SKILL.md,
review-sections.md and plan.md natively in one response, keep additions under
14,000 characters and the summary within ten lines. Budgets unchanged.

 Review the plan in ./plan.md. Its design gaps are vague "clean, modern UI" and "cards and icons", a "hero section with gradient" (AI slop), and missing empty, error, loading, responsive, and accessibility behavior.
 
 Use this non-interactive delivery sequence:
-1. Skip the preamble bash block and any AskUserQuestion calls. Read every lazy section the workflow requires. Review all 7 design passes. Rate each scored design dimension 0-10 and explain what would make it a 10; preserve the unresolved-decisions pass and every required design decision.
-2. EDIT plan.md with the missing design decisions (interaction state table, empty states, responsive behavior, etc.) and the full required review report. Keep the saved review compact: use the canonical tables and decision IDs. Specify each design requirement once; refer to its section or decision ID from other pass rationales, tasks, and report cells instead of repeating that specification. Give concise score rationales and 10/10 explanations. Retain all required report fields, design decisions, diagrams, ratings, and explanations.
+1. Skip the preamble bash block and any AskUserQuestion calls. Read every lazy section the workflow requires: in one response, natively Read plan-design-review/SKILL.md (Read the remainder with offset if the first Read stops early), plan-design-review/sections/review-sections.md (the one lazy section this review requires) and plan.md. No cat, sed, ls, manifest or git exploration is needed. Review all 7 design passes. Rate each scored design dimension 0-10 and explain what would make it a 10; preserve the unresolved-decisions pass and every required design decision.

Keep everything you add to plan.md, including the report, under 14,000 characters.
 3. Persist that complete plan and review with Write before publishing a completed walkthrough or saying a fix is applied. Read plan.md back to verify the saved changes.
-4. Then return a brief, concrete summary of the design changes; do not repeat the full review in the response. This changes presentation only: execute every required pass and lazy-section Read.
