fix(ui): address code review feedback

- ChatMessage: use CSS variable syntax for bg-neo-accent and text consistency
- DebugLogViewer: fix info log level to use --color-neo-log-info
- TerminalTabs: use neo-hover-subtle for hover states instead of text color
- globals.css: fix shimmer effect selector to target .neo-progress-fill
- globals.css: fix loading spinner visibility with explicit border color
- globals.css: add will-change for .neo-btn-yolo performance
- App.tsx: group constants after imports
- NewProjectModal: remove redundant styling (neo-card provides these)
- Add tsconfig.tsbuildinfo to .gitignore and remove from tracking
