refactor(ui): improve message visibility filtering and optimize bundle

- Refactor message filtering logic across AgentExecution, ClaudeCodeSession, SessionOutputViewer, and StreamMessage components to better handle visibility of user messages with tool results
- Replace inefficient every() loop with for-loop for better performance when checking message content visibility
- Add renderedSomething tracking in StreamMessage to prevent rendering empty components
- Optimize SessionOutputViewer with useMemo for displayableMessages filtering
- Remove unused GitHub API response fields (url, html_url, git_url) in Rust agents command
- Add Vite build configuration with manual code splitting for better bundle optimization
- Remove TypeScript expect-error comment for process global variable

These changes improve UI performance by reducing unnecessary re-renders and bundle size through better code splitting.
