v1.10.1

## What's Changed

### Fix: Claude Code marketplace plugin installation (#86)

Fixed a schema validation error in `.claude-plugin/marketplace.json` that prevented `claude plugin install engram` from working.

**The bug:** The `source` object used `"type": "git-subdir"` instead of the correct `"source": "git-subdir"` key expected by Claude Code's marketplace schema.

**Error users saw:**
```
Failed to parse marketplace file: Invalid schema: plugins.0.source: Invalid input
```

This affected all users trying to install Engram via `claude plugin marketplace add` since v1.10.0.

**Thanks to @Jungas80 for the fix!**
