feat(fingerprint): take OS into account

[DennisOSRM]

implements #4404

[Copilot]

Pull request overview

Extends OSRM’s dataset fingerprinting to include an ABI descriptor (operating system, endianness, pointer width) so that .osrm.* datasets prepared on a different platform are rejected with a clear incompatibility error, addressing #4404.

Changes:

• Add OS/endianness/pointer-size fields to util::FingerPrint, bumping the fingerprint magic to force incompatibility with older datasets.
• Treat ABI mismatches as data incompatibility and surface a descriptive error message in both storage::io and storage::tar readers.
• Add unit tests validating ABI compatibility logic, stringification, and that IO/TAR readers reject foreign-ABI fingerprints.
