- Updated the documentation in `docker.md` to provide a detailed explanation of the explicit capability allow-list used for primary containers, emphasizing the rationale behind the selected capabilities and the deliberate omission of `MKNOD`.
- Revised comments in `client.go` and `tools.go` to reflect the decision against using `no-new-privileges`, clarifying its impact on privilege escalation testing and container security.
- Enhanced the overall clarity and completeness of the capability management section to aid understanding of security measures in the Docker-in-Docker setup.
- Added new environment variables `DOCKER_INSIDE_HOST`, `DOCKER_INSIDE_TLS_VERIFY`, and `DOCKER_INSIDE_CERT_PATH` to facilitate secure Docker access for worker containers.
- Updated `.env.example` and `docker-compose.yml` to reflect these new configurations.
- Enhanced backend logic to support the new Docker settings, ensuring proper isolation and security for worker containers.
- Expanded documentation to clarify the usage and implications of the new Docker access configurations.
The container-listing section still described the removed `ls -1` parse,
`pkg/queue`, and the old `[]container.PathStat` return. Update it to the current
`find -print0` + errgroup fan-out returning `ContainerDirListing{Files, Failures,
Truncated}`. Also remove the stale `WithBlock`/`DefaultDialTimeout` paragraph left
above the non-blocking `grpc.NewClient` test — its own next paragraph already
contradicted it.

- Added methods for non-recursive directory listing and file stat operations in the Docker client.
- Implemented a new API endpoint to retrieve files from a running container's directory.
- Updated documentation to reflect new file operations and API changes.
- Introduced data structures for container file metadata and integrated them into the flow file service.
- Enhanced flow file management capabilities with improved synchronization between local and container file systems.
