One-Sentence Summary

This update makes session list loading much faster, especially noticeable when you have many sessions.

New Feature: Session List Performance Optimization

What was updated?

Optimized Session.list() query performance by filtering at the database level instead of loading all data first and then filtering.

What is the session list?

OpenCode saves all historical sessions. When you run opencode attach or view the session list in different project directories, OpenCode needs to load these historical records.

How big is the performance improvement?

Number of Sessions	Before	Now
10	Fast	Fast
50	Slower	Fast
100+	Noticeable lag	Smooth

Simply put: If you have many sessions (dozens to hundreds), this update will make things feel "much faster."
