The REST API for issue field values is simpler and avoids common
pitfalls with the GraphQL approach (needing special headers, node IDs,
option IDs vs names). Key changes:
- Add REST API section as the recommended approach
- Document correct payload format (issue_field_values array wrapper)
- Document that value takes the option NAME not ID for single-select
- List common mistakes (wrong key format, missing wrapper, -f vs --input)
- Move GraphQL to an alternative section (still documented)
- Remove outdated private preview notice (now in public preview)
