chore: move ccw-skill-hub to standalone repository

Migrated ccw-skill-hub to D:/ccw-skill-hub as independent git project.
Removed nested git repos (ccw/frontend/ccw-skill-hub, skill-hub-repo, skill-hub-temp).

+"""Incremental Indexer File Event Processing Tests.
+
+This module tests the file event processing in the incremental indexer,
+covering all file system event types (CREATED, MODIFIED, DELETED, MOVED).
+
+Test Coverage:
+- CREATED events: New files being indexed
+- MODIFIED events: Changed files being re-indexed
+- DELETED events: Removed files being handled
+- MOVED events: File renames being tracked
+- Batch processing of multiple events
