feat(job_scout): score devops/cloud/platform + technical-architect roles

Add positive keywords for the core DevOps/data-platform/cloud lane and
technical-architect titles (cloud/data/platform architect) that previously
scored 0 and surfaced only via the generic "senior" term. Rebalances rankings
so hands-on engineering roles aren't buried under pre-sales "Solutions
Architect" + crypto keyword stacking.
