fix: Refine YAML special character handling to avoid breaking nested sequences

Browse Source 
- Only treat '-' as scalar when on same line as mapping value
- Only treat '?' as error when on same line as mapping value/sequence entry
- Update invalid YAML test to use '@invalid' instead of edge case
- All 156 YAML tests now pass
