Release v4.168.0

Added

• screenplay_declaration_details describes a generated concept's rules: generation.derivedPattern is the anchored regular expression the strategy provably produces (or null with derivedPatternUnknownReason), and generation.rules lists every validation rule in authored order with its proof status (proven, refuted with a witness value, or unproven with a reason), plus diagnosticCode and repair when the compiler reported PLAY0688 or PLAY0689 at that rule. The proofs come from the same rule-consistency check the compiler uses. See declaration details. (part of #618)

Fixed

• The repair-capabilities schema lists PLAY0688 among the repairable diagnostics.
