chore: bump cursor_templates_version to 1.0.4 and update related files

- Updated cursor_templates_version in project-brief.yaml to 1.0.4 for reproducibility.
- Enhanced CHANGELOG with fixes and features for version 1.0.4, including improved template resolution for global installs.
- Updated pubspec.yaml and VERSION file to reflect the new version.
- Added new templates for AGENTS.md and lefthook.yaml to the generator.
- Adjusted tests to include new root-level files in the output.

This release addresses template resolution issues and introduces new repo-level configuration files.
