- Remove symlink hack from cache_file() - no longer needed
- Add get_cache_path() helper for content_hash lookups
- Update all CACHE_DIR / content_hash patterns to use cache_manager
- Fix cache_manager.get_by_content_hash() to check path.exists()
- Fix legacy path lookup (cache_dir not legacy_dir)
- Update upload endpoint to use cache_manager.put()
This ensures cache lookups work correctly for both legacy files
(stored directly in CACHE_DIR) and new files (stored in nodes/).

- Update server.py to use cache_manager for storage
- Update DELETE /cache/{content_hash} to enforce deletion rules
- Add DELETE /runs/{run_id} endpoint for discarding runs
- Record activities when runs complete for deletion tracking

Deletion rules enforced:
