…for pull request triggers (#58) (#309)

* Initial plan

* Implement fork: true/false field for pull-request triggers



* Add fork: false to test-proxy.md workflow as requested



* Implement enhanced fork filtering with array support and glob patterns

- Add forks: []string field support alongside legacy fork: boolean
- Implement glob pattern matching (e.g., "org/*") for organization-level fork allowlists
- Add BuildFromAllowedForks expression builder with startsWith() function support
- Update schema validation to include new forks array field
- Enhanced commentOutProcessedFieldsInOnSection to handle forks arrays
- Add comprehensive test coverage with 11+ new test scenarios
- Apply fork: false to example-engine-network-permissions.md as requested
- Maintain full backward compatibility with existing fork: true/false syntax
- forks array takes precedence over legacy fork field when both present
- All workflows compile successfully and tests pass



* Remove legacy fork: true/false support, keep only forks array with glob patterns



* Support single string and wildcard (*) for forks field in pull request triggers
