fix(community): ShareLink 按钮语义修正 + feed SSR 抗 CF 挑战

[longsizhuo]

背景

用户反馈：

1. Hero 的 ShareLink 按钮主点跳 `/feed`、徽章跳 `/feed/submit`——语义错位（按钮是"投稿"动作，不该去阅读页）
2. 生产 `/feed` 500："This page couldn't load. A server error occurred."

改动

按钮语义修正

• `ShareLink` 主按钮 `/feed` → `/feed/submit`，去掉右上角 "+" 徽章（冗余）
• Join the Resistance 卡片里"访问文章"下方加同构按钮"看看我们最近在读什么" → `/feed`
• 信息架构：Hero 左侧 Contribute + ShareLink = 两个投稿动作；Join 区两个按钮 = 两个阅读入口（文档 + 社区）

Next 16 严格模式修正

• 本地 `/feed` 500 原因：`FeedAuthWrapper` 是 client component 但收 `getCategoryLabel` 函数 prop，Next 16 严格禁止
• 改为 server 端预计算 `slug → 中文` map 传给 client，纯数据

生产 /feed 500 修复

• 原因：Vercel SSR 出口被 Cloudflare Managed Challenge 403，`fetchLinks` 单次失败就抛错
• 对齐 `fetchProfile` 的防御：UA header + 2 次重试（no-store 绕 Next Data Cache）+ cf-ray 日志
• 全败返回 `[]` 而非抛错，页面降级展示空态不崩

i18n

• 新增 `hero.cta.feed`
• 移除失效的 `shareLink.submitAriaLabel`

验证

• 本地 `/` `/feed` `/feed/submit` 都 200
• typecheck 0 errors
• vitest 1/1 绿

Pull request overview

This PR adjusts the homepage/community CTA information architecture and introduces a new Community Feed feature set, while hardening /feed SSR fetching against Cloudflare challenge failures.

Changes:

• Fixes Hero ShareLink CTA semantics (primary action goes to /feed/submit) and adds a separate “reading” entry to /feed.
• Adds Community Feed pages/components: /feed, /feed/submit, /share, user “my shares” pages under /u/[username]/shares, and an admin moderation screen.
• Adds backend rewrites for the new community APIs and expands i18n strings for feed/share UI.

These Link blocks wrap a native <button> inside an anchor, which is invalid HTML (nested interactive elements) and can cause accessibility / keyboard issues. Prefer rendering the link itself as the styled control (or use the shared <Button asChild> pattern used elsewhere, e.g. app/not-found.tsx:31) to avoid nested interactive elements.
