Revamp README header and intro copy

Update README branding and messaging: replace the header image, change the main title to "GitScrum CLI: Status follows Code ⚡", and rewrite the intro to emphasize git-native task management and automation for terminal-first developers. Add a centered hero image and tidy up minor formatting (remove an extra blank line). These are cosmetic/branding improvements to make the CLI positioning clearer.
