Ferricstore.Migration.RedisCompatibility (ferricstore v0.7.0)

Redis migration compatibility matrix and workload assessment helpers.

The matrix is built from FerricStore command metadata first, then from native parser metadata for implemented commands that do not yet have full Redis-style COMMAND metadata. Curated entries are used for important Redis commands that FerricStore intentionally does not support.
