Release v0.6.0 — Visual regression checks · Rosalina7515/ui-modernizer

What's new

Visual regression checks. Two new scripts capture structural + computed-style snapshots of every detected route — before any edit and after — then diff them and surface findings as a "Risks" section in
report.md.
- scripts/visual-snapshot.mjs <before|after> — Playwright-backed; captures up to 5000 elements per route with their tag/role/aria/text/computed-style. Falls back silently if Playwright isn't installed.
- scripts/visual-diff.mjs — compares snapshots and emits .ui-modernizer/risks.json with severity-tagged findings (high / medium / info).
Risk categories (high): missing interactive element, lost aria-label, WCAG AA contrast regression (< 4.5:1).
Risk categories (medium): tag changed, font-size shrunk > 20%, contrast dropped notably.
Risk categories (info): color/background shifted on headings, new elements added (usually intentional).
report.md gains a ## ⚠️ Risks section, per-route, sorted high → medium → info.
New reference: references/visual-regression.md.

SKILL.md — Steps 4/6/7 upgraded from PNG screenshots to JSON visual snapshots + diff. PNG screenshots remain as an optional side step.
scripts/report.mjs — reads risks.json and embeds findings; gracefully omits the section if absent.

Backup / rollback unchanged.
The modernizer never auto-reverts based on risks — they're shown, the user decides.
Existing screenshot scripts kept for users who want PNGs.

视觉回归测试。两个新脚本在改之前和改之后各抓一次每个路由的结构 + 计算样式快照,再 diff 出风险条目,以 "Risks" 章节写进 report.md。
- scripts/visual-snapshot.mjs <before|after> —— 基于 Playwright;每个路由最多抓 5000 个元素的 tag/role/aria/text/computed-style。Playwright 未装时静默降级。
- scripts/visual-diff.mjs —— 比较两份快照,输出 .ui-modernizer/risks.json,带 severity 标签(high / medium / info)。
风险分类(高严重):交互元素消失、aria-label 丢失、WCAG AA 对比度回归(< 4.5:1)。
风险分类(中严重):tag 变了、字号缩水 > 20%、对比度明显下降。
风险分类(info):标题色/背景色变化、新增元素(通常是有意的)。
report.md 新增 ## ⚠️ Risks 章节,按路由展开,高→中→info 排序。
