Commit Message

feat!: remove backward compatibility for legacy pipeline_outputs format (#10249)

Remove temporary deserialization logic for old pipeline_outputs format in
pipeline snapshots. This backward-compatibility layer was introduced in
PR #10096 and marked for removal in Haystack 2.23.0.

BREAKING CHANGE: Pipeline snapshots created before Haystack 2.17.0 will
no longer deserialize correctly. Users must recreate snapshots with the
current Haystack version or manually migrate to the new serialization schema.

Changes:
- Remove conditional deserialization check in Pipeline.run()
- Remove test_load_pipeline_snapshot_with_old_pipeline_outputs_format test
- Add breaking change documentation with migration instructions

The new format uses 'serialization_schema' and 'serialized_data' fields,
consistent with other pipeline state serialization.

Closes #10168
Ref #10096
