Description

When an agent writes N files in quick succession, the file watcher calls loadFile / refreshDir synchronously for each event. This fires N parallel HTTP requests within milliseconds, saturating the browser connection pool and causing UI stalls.

Steps to reproduce

1. Start a session and ask the agent to create or modify 10+ files at once
2. Watch the Network tab — one request per file fires immediately
3. With enough files the browser connection pool backs up and the UI freezes briefly
