fix: skip highlight entries in feed service response

[pnvasanth]

Summary

• Filter out feed data items with type: "highlight" before processing in FeedClient.fetchFeed
• Prevents the new highlight entries (empty post_id) from the feed service from breaking downstream post lookups
• Companion to dailydotdev/daily-feed#806

Test plan

• TypeScript type-check passes (no new errors)
• Verify feed responses with highlights enabled still return correct post data
• Verify highlight entries are filtered out and don't cause DB lookup failures

🍹 The Update (preview) for dailydotdev/api/prod (at 5a4dc3c) was successful.

✨ Neo Explanation

This is a standard production code deployment rolling out a new application version across all 7 services and 38 scheduled jobs, accompanied by the routine creation of database and ClickHouse migration jobs for the new release.

Root Cause Analysis

A new version of the API application has been built and is being deployed to production. Every Kubernetes resource is being updated to reference the new container image, replacing the previous version across all deployments, cron jobs, and one-time migration jobs.

Dependency Chain

The new application version cascades uniformly across the entire workload:

• 7 Deployments (API, background, WebSocket, worker, private, Temporal, personalized digest) are being rolled over to the new image via a standard rolling update.
• 38 CronJobs are having their image reference updated so the next scheduled execution picks up the new code.
• 2 migration Jobs (database and ClickHouse) are being replaced: the old migration jobs tied to the previous version are deleted, and new ones for the current version are created. This is the standard pattern for running schema migrations on deploy.

Risk analysis

No stateful resources (databases, storage, persistent volumes) are being modified or deleted. The migration jobs are one-shot Kubernetes Jobs — the old completed jobs are cleaned up and new ones are created for this release, which is expected behavior. Deployments use rolling updates, so there is no anticipated downtime.
