## What changed
- Resolve shell and unified-exec commands against the trusted plugin roots loaded for each turn.
- Add optional `pluginId` and safe plugin-relative `scriptPath` fields to command execution items and legacy execution events, and propagate them through app-server notifications.
- Include the attribution in command execution analytics while rejecting absolute, unsafe, and unattributed script paths.
## Testing
- Cover attribution for cached curated and remote plugin scripts from command execution through core and app-server events.
- Verify analytics serialization and unsafe-path filtering.
