111 reject consume obligation in output

// PIN (phantom_semantic_checker — mirror of 330_110): an OUTPUT/return may ISSUE
// an obligation (<owned!>) or produce-in-state (<owned>), but may NEVER CONSUME
// one (<!owned>). A discharge consumes an INCOMING obligation; a return has
// nothing incoming to consume, so <!owned> in output is a discharge placed where
// only an issue belongs — nonsense. (Prefix-! reads as discharge, suffix-! as
// issue: the position IS the polarity.)
//
// Desired: a clear polarity rejection at the SEMANTIC phantom checker (not the
// parser). Roadmap red until the wall exists. [diagnostic wording Lars's to finalize]
