Subject: [PATCH] digest email: replace reply/reaction counts with relay URL

- Replace `{{Replies}}`/`{{Reactions}}` stat items in digest.mjml with
  a single `{{RelayUrl}}` item showing the posting relay domain
- src/digest.ts: add `RelayUrl` to template variables, derive from
  existing `relayByEventId` map; strip unused `spec`, `getParentId`,
  `repliesByParentId`, and `context` destructure
- test/digest-reply-stats.test.ts: update assertion to check
  `parentEntry.RelayUrl` instead of `Replies`/`Reactions`
- script/render-preview.mjs: update sample data to use `RelayUrl`
