Improve Docker and development container support

[Nanle-code]

Summary:
The existing container setup should be refined to support a more reproducible development environment for contributors.

Why this matters:
Consistent development environments reduce setup issues and help contributors start working faster.

Proposed work:

• Improve Docker build and runtime consistency
• Document how to run the project in containers
• Validate the container setup with common workflows

Acceptance criteria:

• The container flow works reliably for contributors
• Setup instructions are easy to follow
• Development dependencies are reproducible
