⚡ Bolt: Eliminate N+1 query for thread emails

[schmug]

💡 What: Replaced the sequential getEmail map bottleneck wrapped in a Promise.all with a single getFullThread call in workers/agent/index.ts.
🎯 Why: Reading a complete email thread is an N+1 query problem using the standard DO stubs. For an AI agent building prompt context from thread history, this query overhead introduces significant latency.
📊 Impact: Consolidates thread loading to two optimized SQL queries inside the Durable Object.
🔬 Measurement: Verify agent thread context latency drops, tests continue to pass.

Closing as superseded by #658.

This is one of 7 re-derivations of the same agent thread-fetch change, opened by a Jules persona that has since been paused. #658 is the one kept open: it collapses the fetch to a single Durable Object call and removes the now-unused EmailMetadata import. Every variant edits .jules/bolt.md, so only one can land without conflict.
