feat: add prefer-process-get-builtin-module rule

[ColumbusLabs]

Closes #475.

Summary

• add prefer-process-get-builtin-module for global require(), createRequire bindings, and directly awaited built-in imports
• gate reports to Node.js ^20.16.0 or >=22.3.0
• ignore arbitrary/shadowed/reassigned require and process bindings
• keep the rule report-only because module namespace and require cache semantics can differ
• add tests, documentation, registry entry, and generated README metadata

Validation

• npm test (3,094 passing, 3 pending)
• ESLint, TypeScript, Markdown, and generated-doc checks
• plugin registry readback
• git diff --check
