Document scientific scope for accessible, e-waste-focused Arch ARM cyberdeck

[Copilot]

This PR aligns the repository with the stated project intent: a scientific research cyberdeck focused on accessibility and e-waste reuse, spanning both hardware and software on Linux Arch ARM. It also makes the intended offline/educational capabilities explicit in the main project documentation.

• Problem framing

  • Clarifies the project as a research initiative on accessibility + electronic waste reuse.
  • Defines the cyberdeck as a portable platform covering end-to-end implementation (hardware and software).

• README scope expansion

  • Adds explicit objective and technical scope sections.
  • Captures expected capabilities: offline Wikipedia, offline books, terminal usage, and lab/experimentation programs.
  • Anchors software baseline to Linux Arch ARM and highlights reuse-first hardware direction.

• Resulting documented contract

  • Converts a placeholder README into a concise project definition that contributors can implement against.

## Funcionalidades previstas

- Wikipedia offline
- Biblioteca de livros offline
- Terminal para uso técnico e educacional
- Programas de laboratório e experimentação
- Arquitetura portátil com atenção à acessibilidade
