Rewrote AWK state machine to correctly handle:
- Multiple allowed_nodes sections (removes all of them)
- Comment lines immediately preceding allowed_nodes (discards them)
- Empty lines within allowed_nodes section
- Indented list items and comments
The function now:
1. Buffers comment lines that might precede allowed_nodes
2. When allowed_nodes: is detected, discards buffered comments
3. Skips all content until hitting a non-indented, non-comment line
4. Flushes buffered comments when hitting non-comment content
This ensures running the installer multiple times won't create duplicate
allowed_nodes sections in config.yaml.
Tested with script that verifies duplicate sections are removed correctly.
