fix: Handle JSON/YAML arrays at root level in config extraction

PROBLEM:
- Config extractor crashed on JSON files with arrays at root
- Error: "'list' object has no attribute 'items'"
- Example: save.json with [{"name": "item1"}, {"name": "item2"}]
- Only handled dict roots, not list roots

SOLUTION:
- Added type checking in _parse_json() and _parse_yaml()
- Handle three cases:
  1. Dict at root: extract normally (existing behavior)
  2. List at root: iterate and extract from each dict item
  3. Primitive at root: skip with debug log
- List items are prefixed with [index] in nested path

CHANGES:
- config_extractor.py _parse_json(): Added isinstance checks
- config_extractor.py _parse_yaml(): Added list handling

EXAMPLE:
Before: WARNING: Error parsing save.json: 'list' object has no attribute 'items'
After: Extracts settings with paths like "[0].name", "[1].value"

IMPACT:
- No more crashes on valid JSON/YAML arrays
- Better coverage of config file variations
- Handles game save files, API responses, data arrays
