Enhance documentation with comprehensive feature descriptions and contribution guidelines

[Copilot]

Documentation was missing key details about features, usage, and contribution workflow. Added Toastmasters inspiration link per maintainer request.

README.md

• Features: Documented color transitions (green → yellow → red), progress bar, auto-hiding controls, configurable thresholds, and keyboard shortcuts
• Usage: Step-by-step instructions for timer controls and settings configuration
• Getting Started: Prerequisites (Node.js 18.x+) and installation steps
• Architecture: Technology stack (Next.js 14, TypeScript, Tailwind, shadcn/ui) and project structure
• Resources: Link to Toastmasters Timer Zoom Backgrounds inspiration

CONTRIBUTING.md

• Code Style: TypeScript strict mode patterns, React hooks conventions, formatting rules (2 spaces, single quotes, no semicolons)
• Project Structure: Component hierarchy with descriptions (TalkTimer, TimerDisplay, Footer, ProgressBar)
• Testing Checklist: Manual test requirements (timer controls, fullscreen, color transitions, settings)
• Workflow: Added formatting step (npm run format) to development process
• PR Guidelines: Requirements for titles, descriptions, issue references, and screenshots

The progress-bar.tsx component is listed in the project structure but does not exist in the actual codebase. Based on the repository structure, this component should be removed from the documentation or marked as a planned addition.

Suggested change

	│ ├── footer.tsx # Footer with controls
	│ └── progress-bar.tsx # Progress bar component
	│ └── footer.tsx # Footer with controls

[Copilot]

The progress-bar.tsx component is listed in the project structure but does not exist in the actual codebase. This entry should be removed to accurately reflect the current project structure.

[Copilot]

The ProgressBar component reference should be removed as this component does not exist in the codebase. The progress bar functionality is implemented within the TalkTimer component.

Suggested change

- **ProgressBar** (`components/progress-bar.tsx`): Shows progress at the top of the screen
