feat(job_scout): add data-infra adapters + Oracle manual-check

Add Databricks, Snowflake, Datadog, Elastic, dbt Labs (greenhouse/ashby,
title-filtered). Snowflake slug surfaced the Zürich Observe SWE role.
HashiCorp dropped (IBM acquisition killed public boards); Oracle moved to
MANUAL_CHECK (ORC SPA resists scraping; REST endpoint documented in code).
