Consolidate and organize TypeScript documentation

[ballidev]

Problem

We have too many documentation files in the cc-commands-ts project, making it confusing to know where to find information.

Current Documentation Files

• CLAUDE.md
• CLAUDE/Architecture.md
• CLAUDE/OrchestratorArchitecture.md
• CLAUDE/ServiceArchitecture.md
• README.md

Proposed Solution

Consolidate into exactly 3 authoritative documents:

1. ARCHITECTURE.md

• Core principles (commands are markdown, TypeScript is a tool)
• Service layers and contracts (IOrchestrationService)
• Directory structure
• Dependency injection patterns
• What goes where and why

2. CODING_STANDARDS.md

• TypeScript configuration
• ESLint rules and why they exist
• FAIL FAST principle
• Error handling patterns
• Naming conventions
• Import/export patterns

3. TESTING_STANDARDS.md

• Test structure and organization
• Mocking strategies
• Coverage requirements
• Test-first development process
• Integration vs unit tests

Acceptance Criteria

• All existing documentation consolidated into 3 files
• No duplicate information
• Clear hierarchy and navigation
• Each file has a clear purpose
• Old files removed or archived
