cascade-config-mongodb

MongoDB extension for cascade-config that adds a `.mongodb()` loader to read configuration objects from MongoDB collections using variable substitution in URL, db, collection, and _id fields. Current stable version is 1.2.1. Release cadence is low, primarily maintenance updates. Key differentiator: seamlessly integrates with cascade-config's hierarchical config system and supports environment variable expansion in all connection parameters. Deprecated in favor of newer versions requiring cascade-config >=1.9.0 (since v1.2.0). Only works with MongoDB driver v3 connection strings.
