docs: Standardize module examples to use coder_agent.main

Update all module README files to use coder_agent.main instead of
coder_agent.example for consistency with existing template conventions.

Changes:
- Updated 50+ module README.md files
- Updated root README.md and CONTRIBUTING.md
- Updated examples/templates/main.tf

This ensures copy-paste examples from module docs work seamlessly
with the majority of templates that use "main" as the agent name.
