fix(semver): resolve shirabe-semver compile errors

- Replace RefCell with Mutex in Constraint for thread safety
- Add clone_box() to ConstraintInterface for cloning trait objects
- Propagate Result from Constraint::new() and unwrap at call sites
- Fix VersionParser instantiation (unit struct, not fn)
- Add indexmap dependency to shirabe-semver
