chore: update GitHub Actions workflows and documentation

- Modified build.yml to trigger on changes in 'src/**' and 'src-tauri/**' paths.
- Standardized quotes in package-and-publish.yml for consistency.
- Updated README.md and SUMMARY.md to reflect new branding and added new sections for platform and privacy.
- Introduced new documentation files for platform availability and privacy/security features.
