docs: update development workflow and documentation index

Updated development documentation to reflect current project structure
and simplified setup process.

Changes:
- DEVELOPMENT_WORKFLOW.md: Updated repository URL, simplified setup steps,
  improved project structure documentation, and clarified command descriptions
- README.md: Reorganized as a concise index of available guides, removed
  redundant content now covered in main README and in-app help
- SHUTDOWN_PROCESS.md: Removed (content consolidated into GRACEFUL_SHUTDOWN.md)

These updates make the documentation more accurate and easier to navigate
for new contributors.
