refactor: rename claudia to opcode throughout web server code

- Rename binary from claudia-web to opcode-web in Cargo.toml
- Update all references in justfile (web commands)
- Update console output messages in web_server.rs and web_main.rs
- Update documentation in web_server.design.md

This completes the project rename from Claudia to Opcode.
