- Removed unnecessary blank lines in multiple test files to enhance code clarity and maintainability.
- Adjusted formatting in `subscription.go`, `trace_bench_test.go`, `trace_concurrent_test.go`, `trace_mem_test.go`, `trace_node_test.go`, `trace_space_test.go`, and `trace_subscription_test.go` for consistency.
- Updated benchmark and memory leak detection commands in the Makefile to include both agent and trace components.
- Refactored the manager struct in `manager.go` to support cancellable contexts and added per-space locks for improved concurrency safety.
- Enhanced subscription handling in `subscription.go` to only broadcast updates if there are active subscribers, preventing unnecessary operations.
- Implemented comprehensive disk operations in `local/driver.go` and `store/driver.go` for managing trace nodes, spaces, and logs, including loading, saving, and deleting functionalities.
- Improved README documentation to clarify driver configurations and usage examples for trace management.
