Claude 26ece9cc9b Add library-management module: console app evolved into a Spring Boot 4 REST API

Stage 2 console classes and the shared LoanPolicy, then a Spring Boot 4.1.2 + JPA API
(H2, @Version optimistic locking, problem+json errors). Tests write output/ transcripts
while asserting the same numbers; scripts regenerate everything.
