Summary

In src/auto-reply/usage-bar/template.ts, the module-level fileCache Map holds a live fs.watch watcher for each cached template file path. The cache grows without bound — entries are never evicted, and watchers are only closed in clearUsageBarTemplateCacheForTest().

Reproduction

Source inspection: cacheTemplateFile() at line 146 inserts without checking cache size. Each new file path creates a persistent watcher.

Expected

Add a max size limit and evict the oldest entry (closing its watcher) before inserting new ones.

Scope
