Result 0.1.0

First public release of Result, a small Java 25 library for explicit, typed success and failure values.

Highlights

• Mapping and composition with map, mapErr, andThen, combine, and flatten
• Recovery with recover and recoverWith
• Inspection and folding with inspect, inspectErr, and fold
• Exception capture with Result.from(...), catching Exception without swallowing Error
• Optional, stream, sequencing, and collecting utilities
• Validator and typed error-routing utilities
• Spring Boot integration with Failure and RFC 9457 ProblemDetail responses
• Transactional rollback support when a @Transactional method returns a final Result.Err
• Published to Maven Central
