fix: dev mode relative path

[br-monteiro]

This pull request introduces several improvements to local development workflow and documentation for the project, focusing on Docker integration and developer experience. The main changes are the addition of new subcommands to the onecli wrapper script for building images, running in development mode, and opening an interactive shell inside the container. The documentation is updated to reflect these new workflows, and a .dockerignore file is added to optimize Docker builds.

Wrapper script enhancements:

• Added build, dev, and shell subcommands to the onecli script, allowing for building the Docker image, mounting the local project directory for live code updates, and opening an interactive shell in the container, respectively. Also, a persistent .cache volume is now mounted for all runs. [1] [2]

Documentation updates:

• Updated the README.md to document the new build, dev, and shell subcommands, including usage examples and workflow tips for development without rebuilding the Docker image. [1] [2]
• Improved documentation for running tests and removed redundant expected output section.

Docker build optimization:

• Added a .dockerignore file to exclude unnecessary files and directories from the Docker build context, improving build performance and reducing image size.
