This change adds a new documentation section that sets up the structure for Odoo coding guidelines. It helps teams build toward clearer development standards, which can improve consistency and onboarding over time.

Odoo now avoids enabling a background server mode when a debugger is detected, preventing development sessions from freezing. This helps developers troubleshoot issues more reliably without changing day-to-day business workflows.

When debugging in Eclipse/PyDev with gevent installed, the debugger stalls when GEventServer is started. If we detect something is intercepting tracebacks, we should disable gevent.
