feat: Add Jackson 3.x support

[tgrundle]

Summary

This PR introduces Jackson 3.x support for jackson-dataformat-hal

Motivation

Jackson 3.x adoption is growing, and downstream services need a supported upgrade path without losing existing HAL serialization/deserialization behavior.

What changed

1. Added Jackson 3.x-compatible HAL implementation and wiring.
2. Kept existing Jackson 2.x support intact for current consumers.
3. Updated module structure and build configuration to support multi-version compatibility.
4. Added or updated tests to validate behavior for Jackson 3.x and guard against regressions.

Compatibility

1. Backward compatibility is preserved for existing Jackson 2.x users.
2. Jackson 3.x consumers can now adopt this library without custom forks/workarounds.

Validation

1. Unit and integration tests pass across supported modules.
2. HAL serialization and deserialization behavior verified against existing test coverage.
3. No intentional behavioral changes beyond version support.

Breaking changes

None expected for existing Jackson 2.x consumers.

Notes for reviewers

Please focus review on:

1. Version-specific implementation boundaries.
2. Cross-version behavior parity.
3. Dependency and build configuration changes related to Jackson 3.x.
