* Add standardized Makefile includes and developer documentation
Introduce modular Makefile system (common.mk + operator.mk) for
consistent dev workflows. Standardize CONTRIBUTING.md and
docs/development.md to follow community conventions with clear
separation: contributing guidelines for process, development
guide for technical setup.
- Add common.mk with shared dev workflow targets (make up/down)
- Add operator.mk with AWX-specific variables and targets
- Restructure CONTRIBUTING.md: process, testing requirements, community links
- Expand docs/development.md: customization options table, teardown options,
Molecule testing, bundle generation via make targets
- Simplify README.md contributing section
