chore: remove agenticDigestTweet worker

[idoshamun]

Summary

• Deleted the agenticDigestTweet worker (src/workers/agenticDigestTweet.ts) which auto-generated and posted tweets for agentic digest posts
• Removed worker registration from src/workers/index.ts
• Removed the api.agentic-digest-tweet Pub/Sub subscription from .infra/common.ts
• Deleted associated tests (__tests__/workers/agenticDigestTweet.ts)

The shared Twitter client integration (src/integrations/twitter/clients.ts) is retained as it is still used by majorHighlightTweet.

Test plan

• Build passes (pnpm run build)
• Lint passes with 0 warnings
• No remaining references to agenticDigestTweet or agentic-digest-tweet in codebase

Closes ENG-1343

🍹 The Update (preview) for dailydotdev/api/prod (at 47e9137) was successful.

✨ Neo Explanation

This is a feature removal — the agentic digest tweet worker and its Pub/Sub subscription are being decommissioned — bundled with a routine new-image deployment. ✅ Low Risk (the only consideration is whether any unprocessed Pub/Sub messages need draining before the subscription is deleted).

This PR removes the agenticDigestTweet worker entirely — deleting the worker implementation, its registration in typedWorkers, and the corresponding entry in common.ts. This causes Pulumi to delete the GCP Pub/Sub subscription api.agentic-digest-tweet (which was subscribed to the api.v1.post-visible topic). The worker was responsible for generating and posting AI-written tweets about agentic digest posts via Claude + Twitter.

The remaining changes are a standard rolling deployment: all Kubernetes Deployments and CronJobs are updated to the new image tag (47e9137...), and the migration Jobs are replaced with new ones tagged to the same commit (the old commit-tagged Jobs are deleted and new ones created, which is the normal pattern for one-shot migration jobs).

🔵 Info — Any api.v1.post-visible messages currently queued in the api.agentic-digest-tweet subscription will be lost when the subscription is deleted. If there are unprocessed messages in flight at deletion time, those tweets will never be published. This is intentional if the feature is being retired, but worth confirming no pending messages need draining first.
