Plugin uninstall does not clean cache directory

Description

When uninstalling a plugin using \claude plugins uninstall <plugin>\, the cache directory is not cleaned up.

Steps to reproduce

1. Install a plugin: \claude plugins install telegram\
2. Uninstall it: \claude plugins uninstall telegram\
3. Check cache: Cache directory still exists at \~/.claude/plugins/cache/claude-plugins-official/telegram/\

Expected behavior

Option A: Uninstall should clean everything including cache
Option B: Add \--clean\ flag to allow users to choose thorough cleanup

Current behavior

• \installed_plugins.json\ is updated ✅
• \data/\ directory is cleaned ✅
• \cache/\ directory is NOT cleaned ❌

Workaround

Manually delete cache: \ m -rf ~/.claude/plugins/cache/claude-plugins-official/<plugin>\

Environment

• Claude Code version: Latest
• OS: Windows 11
• Plugin: telegram@0.0.4

Suggestion

Either:

1. Clean cache by default during uninstall
2. Add \claude plugins uninstall --clean\ option
3. Add \claude plugins cache clean <plugin>\ command
