- Added SRI hash injection during frontend build to improve security. - Updated ESLint configuration to include 'navigator' as a global variable. - Introduced a new `settingsStore` to manage user preferences for asset verification. - Enhanced `SoftwareCard` and `VerificationModal` components to display contributor information and security checks. - Updated `verificationStore` to handle expanded toast notifications for detailed verification steps. - Implemented a new `CodeBlock` component for displaying code snippets with syntax highlighting. - Improved API documentation and added new endpoints for fetching software and asset details.
