Updated project name from "web-agent-rs" to "open-web-agent-rs" in configuration files, documentation, and source code. This change ensures consistency across the project and reflects the new naming convention. Removed unused entries from `.gitignore` and adjusted Docker commands accordingly.
Introduce detailed documentation on how input works for agents, including flow, formats, examples, validation, and testing procedures. Update references in the README and agents documentation to link to this new resource.
