Bolt appends text to the end of JS files

Describe the bug

the generated code is not always parsed out correctly and the code file gets text appended like:

</content></file>
</boltArtifact>

Key improvements:

1. Secure file permissions:
   - Config file is created with `0o600` permissions (readable/writable only by owner)
   - Stored in user's home directory (`~/.sifter/config.json`)
   ...

Something then goes wrong and this file becomes possibly locked. Any further changes or manual fixes are automatically reverted to this errored state. I have to reload the project to continue working.

Steps to reproduce

Very intermittent issue. After several hours of work, it happened twice.

Expected behavior

Generated code should not have appended non-code text
