chore: update README and CLI usage for cursor_gen, version bump to 1.0.1

- Changed CLI usage instructions from `dart run cursor_gen` to `cursor_gen` for global activation.
- Updated project-brief.yaml example and README to reflect new command usage.
- Added app_context section in project-brief.yaml for theme variants and RBAC roles.
- Fixed bundled template resolution for local and global installs to prevent 'Template not found' errors.
- Version bump to 1.0.1 with corresponding updates in CHANGELOG and pubspec.yaml.
