[Jobs Match Making] Implement Redis-based matching (Python querying Redis)

[aldbr]

Description

Implement the matching logic using Redis as the data store, with matching logic still in Python. This intermediate step isolates whether performance gains come from the data model or from reducing round-trips.

Results must match the pure Python prototype exactly for the same inputs.

Definition of Done

• Data loader: populate Redis from YAML / synthetic data
• Matching function queries Redis, returns same results as pure Python version
• Correctness tests: both implementations produce identical results on same input (should be covered by existing unit tests)
• Locust benchmark: compare latency/throughput vs pure Python baseline
