Set Selection Endpoint

Set entity selection for indexing.

This determines which entities (databases, schemas, tables) from the discovered schema will be indexed and available for querying.

Special Selection Mode:

• Use "*" in selected_paths to select ALL entities (wildcard selection)
• Example: {"selected_paths": ["*"]} will index the entire discovered schema

Flow:

1. Load current connector and schema_structure
2. Prune schema tree to only include selected paths (or use full schema if "*")
3. Update DB with:
   • selected_entity_paths (user's input)
   • selected_schema_structure (pruned tree or full schema)
   • selection_schema_version (snapshot of current schema_version)
   • selected_schema_version (incremented counter)
4. Return pruned schema

After selection, user must call POST /{connector_id}/index to apply changes.

Requirements:

• User must have admin access to connector's org
• Connector must exist with schema_structure (discovery completed)

WARNING: This does NOT auto-include FK targets! If you select tables with foreign key relationships, you must manually select the referenced tables or risk dangling references in the indexed schema.
