[#499] Add notification for new storyline created

[realproject7]

Summary

• Added notifyNewStoryline() to lib/notifications.server.ts — sends "New story published" / "{title}" by {author} is now on PlotLink with target /story/{storylineId} and notification ID pl-new-storyline-{storylineId}
• Updated backfill cron to call notifyNewStoryline() on StorylineCreated events instead of notifyNewPlot() (which was sending a generic "New Genesis published" message)
• Author display uses truncated wallet address (0x1234…5678)

Test plan

• Verify notifyNewStoryline sends correct title/body/targetUrl via backfill cron
• Confirm existing notifyNewPlot still fires for PlotChained events
• Check notification ID uniqueness (pl-new-storyline-{id})

Verdict: REQUEST CHANGES

Summary

The new trigger is wired into the right backfill path, but the notification body does not match the copy requested in issue #499 / the T1 assignment. The implementation currently truncates both the title and author before sending.

Findings

• [medium] notifyNewStoryline() rewrites the requested body instead of sending "{title}" by {author} is now on PlotLink.
  • File: lib/notifications.server.ts:175
  • Suggestion: Send the full title and author values in the body, or explicitly document and test a notification length constraint before changing the requested copy.

Decision

Requesting changes because the acceptance criteria call for the correct notification body, and the current helper intentionally changes that body for longer titles/authors.

Verdict: APPROVE

Summary

The requested change is resolved. notifyNewStoryline() now sends the exact body specified in issue #499, and the backfill cron triggers it on StorylineCreated events.

Findings

• None.

Decision

Approve because the new notification helper, notification ID, deep link, and backfill trigger now match the issue requirements.
